Don't include expected results in libm-test test names

[Joseph S. Myers]

This patch stops libm test names, as used in libm-test-ulps files,
from including the expected result of the test.  This is with a view
to most expected results being generated automatically by MPFR/MPC in
future separately for each floating-point format: then the text of the
expected result for a given input will differ slightly between
floating-point formats, but if the input is exactly the same it's
still good for them to be considered the same test for libm-test-ulps
files.

Tested x86_64 and x86.  I updated all the libm-test-ulps files using
sed (and running gen-libm-test.pl -n on them in case any consequent
reordering was needed); full diff attached gzipped, since it's nearly
4MB uncompressed.  Note that for the actual move to MPFR-based
generation of expected values (probably not for 2.18), it will be
necessary to regenerate all the libm-test-ulps files from scratch, as
all test inputs for MPFR-based tests will I expect end up in hex float
format.

This patch approximately halves the sizes of the libm-test-ulps files
(in bytes, of course the size in lines doesn't change significantly).
