As for exp/exp2 benchmark, this patch add two benchmark for pow:
one which measures thoughput and one which measures latency.
The input data is the same as powf.
Test: ran 32-bit and 64-bit x86 tests on host

Similar to exp/exp2, this patch add two benchmarks for log and log2:
one which measures thoughput and one which measures latency.
The input data is based on logf/log2f one (reduced trace based on 2.8
billion samples extracted from specpu2017 521.wrf_r benchmark).

This patch add two benchmarks for both exp and exp2, one which measures
thoughput and one which measures latency. The latency benchmark works by
creating a dependency on the previous iteration and with a zero multiply
to avoid changing the input value.
The input is based on expf/exp2f benchmark (reduced trace based on 2.4
billion samples extracted from specpu2017 521.wrf_r benchmark).

Similar to expf/exp2f, this patch add two benchmarks for sinf, cosf, and
sincosf: one which measures thoughput as default and one which measures
latency.
The input in 512 random value divided in 8 ranges:
1. 0.0 <= x < 0.1
2. 0.1 <= x < 0.7
3. 0.7 <= x < 3.1
4. -3.1 <= x < 3.1
5. 3.3 <= x < 33.3
6. 100.0 <= x < 1000.0
7. 1e6 <= x < 1e32
8. 1e32 < x < FLT_MAX

As for expf/exp2f benchmark, this patch add two benchmark for powf:
one which measures thoughput and one which measures latency.

Instead of requiring the need to maintain a list of all the benchmarks,
add a programmatic way to generate all of the benchmarks.
This generation runs the benchmarks in alphabetical order.
Add a new macro BIONIC_BENCHMARK_WITH_ARG that will be the default argument
to pass to the benchmark. Change the benchmarks that require default arguments.
Add a small example xml file, and remove the full.xml/host.xml files.
Update readme.
Test: Ran new unit tests, verified all tests are added.

These are still needed for backwards compatibility with code built by old
versions of the NDK, but we don't need to pollute the headers with them.
Also lose the hand-written code for these. The compiler-generated code
is either the same or better, and no new code is calling these functions
anyway.
Bug: N/A
Test: ran tests

Don't enable the inlines when building libm itself. Otherwise clang gets
upset by seeing both an inline and a non-inline definition.
This reverts commit c5deb0f883.

Also remove cruft meant to support long-obsolete compilers. More
benchmarks.

Changes:
- Modify the benchmarks to derive from a single Benchmark object.
- Rewrite the main iteration code. This includes changing the iteration
code to use the actual total time calculated by the benchmark as a basis
for determining whether there are enough iterations instead of using
the time it takes to run the benchmark.
- Allow benchmarks to take no argument, int, or double.
- Fix the PrettyInt printer for negative integers.
- Modify the max column width name to include the whole name including
the arg part.
- Reformat property_benchmark.cpp in line with the rest of the code.
- Modify a few of the math benchmarks to take an argument instead of
separate benchmarks for the same function with different args.
- Create a vector of regex_t structs to represent the args all at
once instead of when running each benchmark.
This change is in preparation for adding new math based benchmarks.
Tested by running on a nexus flo running at max using the new code
and the old code and comparing. All of the numbers are similar, but
some of the iterations are different due to the slightly different
algorithm used.

This patch fixes the ARM64 ABI for libm. fenv_t is now split in 32bit status
and 32bit control. This mirrors the AArch64 FPU control and status
registers (FPCR, FPSR).
The patch also refactors the libm implementation for ARM64 into a finer
grained control over the FPU registers.
Bionic-benchmarks has been expanded with 3 more benchmarks for floating
point operations. The new libm implementation for ARM64 performs better
over all the math benchmarks available.

Also move isinf and isnan into libc like everyone else.
Also move fpclassify to libc like the BSDs (but unlike glibc). We need
this to be able to upgrade our float/double/long double parsing to gdtoa.
Also add some missing aliases. We now have all of:
isnan, __isnan, isnanf, __isnanf, isnanl, __isnanl,
isinf, __isinf, isinff, __isinff, isinfl, __isinfl,
__fpclassify, __fpclassifyd, __fpclassifyf, __fpclassifyl.
