Fangrui Song 70f9cfc857 [builtins][test] Delete unneeded file headers
We don't add file headers to tests. The comments are useless as well -
their purpose can be easily inferred from the filenames.

Dan Liew 5be7eb3ab4 [Builtins] Provide a mechanism to selectively disable tests based on whether an implementation is provided by a builtin library.
Summary:
If a platform removes some builtin implementations (e.g. via the
Darwin-excludes mechanism) then this can lead to test failures because
the test expects an implementation to be available.

To solve this lit features are added for each configuration based
on which sources are included in the builtin library. The features
are of the form `librt_has_<name>` where `<name>` is the name of the
source file with the file extension removed. This handles C and
assembly sources.

With the lit features in place it is possible to make certain tests
require them.

Example:

```
REQUIRES: librt_has_comparedf2
```

All top-level tests in `test/builtins/Unit` (i.e. not under
`arm`, `ppc`, and `riscv`) have been annotated with the appropriate
`REQUIRES: librt_has_*` statement.

Chandler Carruth 57b08b0944 Update more file headers across all of the LLVM projects in the monorepo
to reflect the new license. These used slightly different spellings that
defeated my regular expressions.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Weiming Zhao 9b7bbeca48 [Builtin] Implement lit-test support (part 1 of 2: test cases update)
Original r297566 is splitted into two parts.
This is part one, which adds "RUN" command for test cases.
Unit/arm/call_apsr.S is updated to support thumb1.
It also fixes a bug in arm/aeabi_uldivmod_test.c
gcc_personality_test is XFAILED as the framework cannot handle it so far.
cpu_model_test is also XFAILED for now as it is expected to return non-zero.

TODO: A few tests are XFAILed for armhf and aarch64.
We need further investigating.  [1,2] Tracks the issue.

Weiming Zhao d77a6730b1 [Builtin][ARM] #ifdef ARM vfp tests and cpu_model_tests
Summary:
Add in #ifdef to exclude cpu_model_test on non-X86 and  *vfp_test on ARM targets without VFP support.

This is consistent with other target-specific tests that print "Skipped" if not supported.

Oleg Ranevskyy 8a8b7b6df7 [compiler-rt][tests] cpu_model_test.c test fails to compile if X86 is not clang's default target
Summary:
test/builtins/Unit/cpu_model_test.c tests the X86 specific builtin `__builtin_cpu_supports`.
It fails if the clang's default target is not X86.

The proposed patch adds an additional requirement for the X86 target to the test, making lit ignore the test if the target is different.

Alina Sbirlea 36f57fbc66 Add runtime support for __cpu_model (__builtin_cpu_supports)
Summary:
    This aims to add support for __cpu_model and address Bug 25510. It uses
    the code from lib/Support/Host.cpp for cpu detection, and creates
    __cpu_model with that info.

    Tested on OSX and built on Linux as well (though libgcc is the default).
    The use of "asm" required -std=gnu99, hence the cmake change. Corrections
    on better addressing this are welcome.

    Previously reverted, up for review again to iron out outstanding issues.

Alina Sbirlea 9ebebce2df Add runtime support for __cpu_model (__builtin_cpu_supports)
Summary:
This aims to add support for __cpu_model and address Bug 25510. It uses
the code from lib/Support/Host.cpp for cpu detection, and creates
__cpu_model with that info.

Tested on OSX, it builts successfully, but the current version does
*not* resolve Bug 25510. The __cpu_model symbol is present in the
library but it only gets loaded with -all_load. This patch will not land
until this issue is clarified.

Built on Linux as well (though libgcc is the default). The use of "asm"
required -std=gnu99, hence the cmake change. Corrections on better
addressing this are welcome.

Note: See additional comments on D20988 (committed as r271921).
