Add headers for _Float64, _Float32x testing [committed]

[Joseph Myers <joseph at codesourcery dot com>]

This patch adds the headers required for testing _Float64 and
_Float32x function aliases (using double ulps).  The corresponding
makefile support will be included in the patch that actually adds
those aliases; there doesn't seem much point in adding makefile
conditionals for testing something that will be available
unconditionally.

In conjunction with other _Float64 / _Float32x changes, tested for
x86_64 and with build-many-glibcs.py.  Committed.

	* math/test-float32x.h: New file.
	* math/test-float64.h: Likewise.
