At the moment we collect a lot of compilation units (one per binding
expression!), which for long running QML accumulates and creates a horrible
performance when trying to retrieve back traces. There is work in progress
to reduces the number of units down to one per QML file, and then the
fixed sorted QVector might proof to be a more efficient data structure
for the lookups.
But until that code lands, this patch proposes to use a QMap instead for the
time being, that tracks all functions. This brings down the qtquickcontrols
auto-test run from 2.5 minutes to just under a minute on my machine.

QQmlError provides the same functionality, so let's rather
use that where required. Remove the dependency of
codegen onto the ExecutionContext that was only
required for error handling.

Runtime strings are identifiers, but they still require to be marked. Keep
track of all compilation units in the engine (one per file) and mark its
run-time strings.

This reduces memory pressure, keep engine->functions small and thus makes back
trace lookup faster. It became visible for example in the QtQuickControls
auto-tests that use plenty of loaders and we ended up with 30k+ functions.

Move the v4 engine classes from a subdir of qml/qml into
two subdirs (compiler and jsruntime) of the qml module
Remove an unsued qv4syntaxchecker class, and move
the moth code directly into compiler.
