b662280aaf Use __builtin_* in <math.h>. 
Also remove cruft meant to support long-obsolete compilers. More
benchmarks.

45789b63db libm: Add hardware sqrt, ceil, floor and trunc for x86 & x86_64 
Add hardware implementations for sqrt, ceil, floor and trunc for
x86 and x86_64. These routines, and in particular sqrt are much
faster than the BSD C language versions of these functions.

Fixed whitespace errors.

Revised x86 versions with respect to alignment.
Rebased for Android 5.0

b8ee16f1dc Fix our <complex.h> support. 
We build libm with -fvisibility=hidden, so we weren't exporting any
of the <complex.h> functions.

We also weren't building many of the functions anyway.

We were also missing the complex inverse trigonometric functions.

And because we didn't even have perfunctory "call each function once"
tests, we didn't notice that we weren't exporting any symbols, so this
patch adds at least that level of testing.

5f5cc45cf0 Fix <features.h> (_BSD_SOURCE and _GNU_SOURCE). 
<features.h> is supposed to take user-settable stuff like _GNU_SOURCE
and _BSD_SOURCE and turn them into __USE_GNU and __USE_BSD for use in
the C library headers. Instead, bionic used to unconditionally define
_BSD_SOURCE and _GNU_SOURCE, and then test _GNU_SOURCE in the header
files (which makes no sense whatsoever).
