Add header for _Float32 testing.
This patch adds the header required for testing _Float32 function aliases, using float ulps. The corresponding makefile support will be included in the main patch that enables those aliases. In conjunction with other _Float32 changes, tested for x86_64 and with build-many-glibcs.py. * math/test-float32.h: New file.
