361847f9ac Fix the x86_64 fenv.h. 
We should clean all the fenv.h files up, but not now. I've raised
bug 11050744 as a reminder.

a0ee07829a Upgrade libm. 
This brings us up to date with FreeBSD HEAD, fixes various bugs, unifies
the set of functions we support on ARM, MIPS, and x86, fixes "long double",
adds ISO C99 support, and adds basic unit tests.

It turns out that our "long double" functions have always been broken
for non-normal numbers. This patch fixes that by not using the upstream
implementations and just forwarding to the regular "double" implementation
instead (since "long double" on Android is just "double" anyway, which is
what BSD doesn't support).

All the tests pass on ARM, MIPS, and x86, plus glibc on x86-64.

90e10d41c4 Rewrite <fenv.h> for ARM. 
The old code was one big no-op.

0f7809d5c3 Start cleaning up libm. 
We have two copies of fenv.h for every architecture, one of which
isn't used. We also have unused makefiles and files for architectures
we don't support.

This patch removes all the obviously useless files.

4e86ebb4b6 Had include/arm/fenv.h, but missed include/mips/fenv.h. 
Needed for the device-build for LLVM's constant folding pass.

6cda7b6249 Bionic: x86: Fix libm macro definitions 
http://code.google.com/p/android/issues/detail?id=19276

GCC would remove inline asm due to lack of knowledge
of FPU register changes.
