Last 4 patches for BZ #14117

[H.J. Lu]

Hi,

There are 4 patches remaining for

http://sourceware.org/bugzilla/show_bug.cgi?id=14117

fpu/bits/fenv.h changes are straight forward:

http://sourceware.org/ml/libc-alpha/2012-06/msg00106.html
http://sourceware.org/ml/libc-alpha/2012-06/msg00113.html

It simply checks __SSE_MATH__ in x86_64/fpu/bits/fenv.h
before using SSE insn in feraiseexcept.

Changes for bits/mathinline.h:

http://sourceware.org/ml/libc-alpha/2012-06/msg00108.html
http://sourceware.org/ml/libc-alpha/2012-06/msg00114.html

combine i386/fpu/bits/mathinline.h with
x86/fpu/bits/mathinline.h.  It also fixes:

http://sourceware.org/bugzilla/show_bug.cgi?id=14050

To help review, I can post another patch to add x86-64
support to i386/fpu/bits/mathinline.h.
