Solaris 10 uses int32 for the Pw_uid and Pw_gid fields of Passwd,
    but most systems, including Solaris 11, use uint32.  Force uint32

This commit adds the -fmacro-prefix-map option that allows remapping of file
names in __FILE__, __BASE_FILE__, and __builtin_FILE(), similar to how
-fdebug-prefix-map allows to do the same for debug information.

Additionally, it adds -ffile-prefix-map which can be used to specify both
mappings with a single option (and, should we need to add more -f*-prefix-map
options in the future, those as well).

The builtin-bswap-1.c and builtin-bswap16-1.c are pretty annoying at the moment.
They force an explicit armv6 option that is a thumb1 target, so if you're testing a toolchain
configured with something like --with-cpu=cortex-a15 --with-float=hard --with-mode=thumb
you'll get those pesky errors about Thumb1 hard-float not being implemented, even though
the tests don't relate to floating-point functionality at all. I *think* this is also due
to the wrong order of dg-options and dg-require-effective-target directives that might
end up not doing a proper effective target check.

The solution in this patch is to commonise the code and create a couple of tests for each.
One tests an armv6t2 target. This allows us to test an ARM or a Thumb2 target.
The second one sets an armv6-m target, which is a Thumb1 target.
The dg-add-options machinery for arm_arch_v6m knows how to add the right -mfloat-abi=soft option.

With this patch we end up testing all of ARM, Thumb1, Thumb2 codegen whereas before we only
ever tried testing Thumb1, if the multilib options happened to line up just right, and would
give an ugly error otherwise.  Now, if the multilib options don't allow the test it should just
appear as UNSUPPORTED.

    compiler: pass int to makechan, call makechan64 when appropriate
    
    The update to 1.10beta1 changed makechan to take int instead of int64,
    and added a makechan64 call for large values.  Since the size is the
    last argument to makechan, the old compiler which always passed a
    64-bit int worked fine on 64-bit systems and little-endian 32-bit
    systems, but broke on big-endian 32-bit systems.  This CL fixes the
    compiler to use the appropriate types.
    
    This fixes GCC PR 83787.
