Joseph Myers 1f79bc4838 Change fromfp functions to return floating types following C23 (bug 28327) 
As discussed in bug 28327, C23 changed the fromfp functions to return
floating types instead of intmax_t / uintmax_t.  (Although the
motivation in N2548 was reducing the use of intmax_t in library
interfaces, the new version does have the advantage of being able to
specify arbitrary integer widths for e.g. assigning the result to a
_BitInt, as well as being able to indicate an error case in-band with
a NaN return.)

As with other such changes from interfaces introduced in TS 18661,
implement the new types as a replacement for the old ones, with the
old functions remaining as compat symbols but not supported as an API.
The test generator used for many of the tests is updated to handle
both versions of the functions.

Tested for x86_64 and x86, and with build-many-glibcs.py.

Also tested tgmath tests for x86_64 with GCC 7 to make sure that the
modified case for older compilers in <tgmath.h> does work.

Also tested for powerpc64le to cover the ldbl-128ibm implementation
and the other things that are handled differently for that
configuration.  The new tests fail for ibm128, but all the failures
relate to incorrect signs of zero results and turn out to arise from
bugs in the underlying roundl, ceill, truncl and floorl
implementations that I've reported in bug 33623, rather than
indicating any bug in the actual new implementation of the functions
for that format.  So given fixes for those functions (which shouldn't
be hard, and of course should add to the tests for those functions
rather than relying only on indirect testing via fromfp), the fromfp
tests should start passing for ibm128 as well.
