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.

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.

Match the builtins that GCC provides for IEEE754 quad precision
on MIPS64. Also, enable building them with clang as PR20098 is resolved.
Disable tests for xf and xc modes as MIPS doesn't support that mode in
hardware or software.

Many things were broken:
- We stopped building most builtins on Windows in r261432 for reasons
that are not at all clear to me. This essentially reverts that patch.
- Fix %librt to expand to clang_rt.builtins-$arch.lib on Windows instead
of libclang_rt.builtins-$arch.a.
- Fix memory protection tests (trampoline, enable executable, clear
cache) on Windows. One issue was that the MSVC incremental linker
generates ILT thunks for functions with external linkage, so memcpying
the functions into the executable stack buffer wasn't working. You
can't memcpy an RIP-relative jump without fixing up the offset.
- Disable tests that rely on C99 complex library functions when using
the MSVC CRT, which isn't compatible with clang's C99 _Complex.
In theory, these could all be separate patches, but it would not green
the tests, so let's try for it all at once. Hopefully this fixes the
clang-x64-ninja-win7 bot.

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.

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.
