  Remove math-finite.h redirections for math functions since the most
commonly used math functions no longer use multiple entry points.

Passes buildmanyglibc (so far, it's still running). OK for commit?

2019-05-08  Wilco Dijkstra  <wdijkstr@arm.com>

        * bits/math-finite.h: Delete file.
        * math/Makefile: Remove math-finite.h from installed headers.
        * math/math.h: Remove math-finite.h inclusions.
        * sysdeps/ia64/fpu/bits/math-finite.h: Delete file.

If the header is removed, the tests of it should be removed as well (both 
the general support for all the libm-test tests running to test those 
function variants, including the TEST_FINITE code, and some specific tests 
that also have finite-math-only variants built with either 
-ffinite-math-only or -D__FINITE_MATH_ONLY__=1).

This is not otherwise a review of the patch.  A revised patch version 
would still need review and consensus on the change to be achieved.
