Change the AT_All_XXX to AT_ALL_XXX.
Change the name of the from_prot and to_prot parameters to be more
descriptive.
Add a few extra large page sizes. Without this, it jumps from a
relatively small size to an extreme large size and nothing in
between.
Clang-format modified the args_shorthand initialization.
Test: Ran benchmarks on device.

Add benchmarks to monitor performance of the syscalls which are frequently
used in Android. These benchmarks will help Android kernel team to catch
syscall performance regressions and flagging them early. They can also
be used to compare different kernel versions.
Add mmap/munmap syscall benchmarks as a starting point. mmap and munmap
are among most frequently used syscall in Andoird. Specific parameters
were also chosen based on the frequency of their use in Android.

Currently, if a test is created like this:
BIONIC_BENCHMARK_WITH_ARG(BM_bench, "16");
Everything works as expected, a benchmark is created of BM_bench/16.
However, it is not possible to specify a benchmark should be called with
one argument, but iterate over different values. The example:
BIONIC_BENCHMARK_WITH_ARG(BM_bench, "16 32");
Creates a single benchmark run with two arguments:
BM_bench/16/32
This change modifies the algorithm to make it possible to create multiple
instances of the benchmark iterating over each argument as a single
argument. After this change, two benchmarks are executed:
BM_bench/16
BM_bench/32
To do the previous behavior, use:
BIONIC_BENCHMARK_WITH_ARG(BM_bench, "16/32");
This will create a single benchmark with two args. This format does
not support spaces in the args, so "16 / 32" is not valid.
Modified the test_small.xml to use the new format.
Test: All unit tests pass.

Per Wilco Dijkstra at ARM, 16 and 32 byte copies are much more common
than 8 or 64.

This patch add an option to use the pre-define set of ranges along
with macros AT_ONEBUF_MANUAL_ALIGN_* and AT_TWOBUF_MANUAL_ALIGN1_*.
The size argument can be either a number or a string representing
the sets of values:
* SMALL for values between 1 and 256.
* MEDIUM for values between 512 and 128KB.
* LARGE for values between 256KB and 2048KB.
Test: Ran new string test suite with a single bionic iteration.

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
Test: ran 32-bit and 64-bit x86 tests on host

Make sure that all the variables are properly initialized.
Remove the code that verifies the core to enable using get_schedaffinity
since that make it impossible to change the cpu for different tests.
Change the cpu_to_lock to an int, it really didn't need to be a long.
Fix a few missing tests.
Test: Ran unit tests.
Test: Built the tests and ran on different cpus, verifying that the
Test: chosen cpu was correct.
Test: Created an xml file that had different cpus for different tests
Test: and verified that it locked to each cpu properly.

There were a bunch more unreasonable/incorrect ones, but these ones
seemed legit. Nothing very interesting, though.
Bug: N/A
Test: ran tests, benchmarks
Change-Id: If66971194d4a7b4bf6d0251bedb88e8cdc88a76f
Also fix the tests for some missing benchmarks that have been
added recently.
Test: Ran bionic benchmarks tests and all pass.
Test: Ran bionic benchmarks to verify that there are no crashes.

Add a bunch of extra options to allow greater flexibility for creating
benchmarks. Add a pattern option that can be used to represent any
one buffer or two buffer possibility. This should fully replace the
functionality of microbench.
Add a single option for one buffer benchmarks and two buffer benchmarks
that represents all of the possible options to run a string benchmark.
Add a string test suite that includes all string benchmarks using the
above option.
Test: New unit tests to cover all the new options, and all pass.
Test: Ran new string test suite with a single bionic iteration.

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.

- Add a default xml file to run if nothing is specified on the command-line.
- Add a way to specify a xml file in suites without having to specify the
full path name.
- Move all of the test xml files into their own directory.
- Add the suites directory for to glibc benchmarks.
- Add a new test for help data.
- Modify the full suite test to verify the default xml is chosen and use
the real full.xml instead of the test one. Delete the test_full.xml.
- Move the property tests to the end of the suite.
- Add skipping of xml comments.
Test: Ran the unit tests and ran the bionic benchmarks.
