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.

Reid Kleckner dffe5a3807 Compile and test i128 math builtins for Win64
Summary:
Windows has always been LLP64, not LP64, so the macros were incorrect.
Check for _WIN64, since AArch64 sets that too.

The tests have to be fixed up in two main ways:
1. Use 'ULL' suffixes to avoid sign extension when passing hex literals
   with the sign bit set to signed 128 arguments. Clang
   -fms-compatibility makes such hex literals signed, not unsigned.
2. Disable various tests for 80-bit long double interoperation with i128
   values.

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.

Derek Schuff eb0ebc367e Add COMPILER_RT_ABI attribute to declarations of builtin functions in unittests
Summary:
This makes their local declarations match their definitions for ARM targets,
where they have a different calling convention.

This really only affects functions that use floating point types (since the
runtime functions use soft-float, and some targets may default to hard-float)
but it seemed good to make it uniform and do the int-only ones too.
