Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with
move semantics, its name is misleading. Q_RELOCATABLE_TYPE was
introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE
is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE
by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this
patch should have no impact on users.

This leads to "make benchmark" actually running the benchmark, which

lines from the same configurations; those surely only configure how
the test code is compiled, which is more or less pointless; it's the
code under test whose debug/release state matters, and I don't suppose
that's affected by the build config of the test code.

Commit 12c5264d9a fixed the calculation of
SHA-3 in QCryptographicHash: we were previously calculating Keccak.
Unfortunately, turns out that replacing the algorithm wasn't the best
idea: there are people who need to compare with the result obtained from
a previous version of Qt and stored somewhere. This commit restores the
enum values 7 through 10 to mean Keccak and moves SHA-3 to 12 through
15. The "Sha3_nnn" enums will switch between the two according to the
QT_SHA3_KECCAK_COMPAT macro.
[ChangeLog][Important Behavior Changes] This version of Qt restores
compatibility with pre-5.9.0 calculation of QCryptographicHash
algorithms that were labelled "Sha3_nnn": that is, applications compiled
with old versions of Qt will continue using the Keccak algorithm.
Applications recompiled with this version will use SHA-3, unless
QT_SHA3_KECCAK_COMPAT is #define'd prior to #include
<QCryptographicHash>.
[ChangeLog][Binary Compatibility Note] This version of Qt changes the
values assigned to enumerations QCryptographicHash::Sha3_nnn.
Applications compiled with this version and using those enumerations
will not work with Qt 5.9.0 and 5.9.1, unless QT_SHA3_KECCAK_COMPAT is
defined.

Do a check first if we need to transform before doing the transform.
This means we won't detach when transforming data that is already
correct.
And instead of using QChar, use our own hand-rolled table. In a proper
LTO build, the QChar calls would be resolved to a lookup of the Unicode
data, but not many people do LTO builds, Therefore, this means a great
speed-up is achieved by simply avoiding the function call. The extra
gain in performance comes from the simpler translation table instead of
the more complex full-Unicode data.
Also as a consequence, this changes the handling of two characters in
Latin 1: 'ß' should be uppercased to "SS" but we won't do it, and 'ÿ'
can't be uppercased in Latin 1 ('Ÿ' is outside the range).
Benchmarking is included. Comparing the Qt 5.4 algorithm to the new code
is almost 20x faster. Other alternatives are included in the benchmark
and are all faster than the current code, though slower than the new
one. While all of them could compress the tables to be smaller or shared
between uppercasing and lowercasing, they would also expand to more code
(though probably less than the extra bytes required in the full
translation table). In the trade-off, I decided to go with simplicity
and most efficient code.

According to my profiling of Qt Creator, qHash and the SHA-1 calculation
are the hottest spots remaining in QtCore. The current qHash function is
not really vectorizable. We could come up with a different algorithm
that is more SIMD-friendly, but since we have the CRC32 instruction that
can read 32- and 64-bit entities, we're set.
This commit also updates the benchmark for QHash and benchmarks both
the hashing function itself and the QHash class. The updated
benchmarks for the CRC32 on my machine shows that the hashing function
is *always* improved, but the hashing isn't always. In particular, the
current algorithm is better for the "numbers" case, for which the data
sample differs in very few bits. The new code is 33% slower for that
particular case.
On average, the improvement (including the "numbers" case) is:

Changed the processing of non-character code handling in the UTF8 codec.
Non-character codes are now accepted in QStrings, QUrls and QJson strings.
Unit tests were adapted accordingly.

When calling intersect() on a large (1000000 items) QSet, with a small
(1000 items) QSet as the argument, the function takes signifcantly
longer than when the operand and the argument are reversed. This is
because the operand set is always iterated over in its entirety.
This patch changes intersect() to iterate over the smaller set. This
reduces the large operand scenario's benchmark to ~0.000063
milliseconds, compared to the current ~134 milliseconds:
1000000.intersect(1000) = empty: 0.000063 (was 134)
1000.intersect(1000000) = empty: 0.000039 (was 0.000036)
1000000.intersect(1000) = 500: 0.10 vs (was 130)
1000.intersect(1000000) = 500: 0.023 vs (was 0.093)
1000000.intersect(1000) = 1000: 0.20 vs (was 139)
1000.intersect(1000000) = 1000: 0.017 vs (was 0.016)

It was only used for toUpper/toLower but always computed in the
constructor, including QString::toLatin1 conversion and allocations.
This needlessly slows down all other uses, including supposedly "cheap"
operations QString::toDouble, or accesses inside QResourceFileEngine.
The benchmarks indicates that doing it always when needed is bearable.
There's still a lot of improvement potential on these code paths.

excluding 3rdparty, test-data and auto generated code.
Note A): the only non 3rdparty c++-files that still
have trailing whitespace after this change are:
* src/corelib/codecs/cp949codetbl_p.h

Note B): in about 30 files some overlapping 'leading tab' and
'TAB character in non-leading whitespace' issues have been fixed
to make the sanity bot happy. Plus some general ws-fixes here
and there as asked for during review.

In case somebody uses QVector as a stack, it is not fair to have
takeLast, removeLast and pop_back to do way too much work.
This is still very slow compared to std::vector::pop_back
(mostly due implicit sharing), however it is more than a
factor faster than before.

We can insert directly on the most left-most Node.
We always enforce an insert here (unlike the insert call),
but that is not a problem since the keys in a std::map are unique.

This suggestion keeps track of the most left node.
The point is that constBegin() becomes a lot faster.
That speeds up iteration a bit, and makes it O(1) to get the
first element. The penalty in insert and remove is very small.
On large trees it seems to be less than 1%.
It should be noticed that constBegin() is a very common hint
on my planned change to 5.1, and this opperation will without
this patch cost 2 x log N. One when the user calls the hint
with begin - and one where it is compared with begin.
Other std::maps has a very fast begin(). E.g
http://www.cplusplus.com/reference/stl/map/begin/
(begin with constant time)
