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 8c78ca2e8f [builtins] Get the builtins tests passing on Windows
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.

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.

Michal Gorny b81980a376 [test] Fix page address logic in clear_cache_test
Fix the logic used to calculate page boundaries in clear_cache_test to
use correct masks -- e.g. -4096 rather than -4095. The latter gives
incorrect result since:

  -4095 -> 0xfffff001
  -4096 -> 0xfffff000 (== ~4095)

The issue went unnoticed so far because the array alignment caused
the last bit not to be set. However, on 32-bit x86 no such alignment is
enforced and the wrong page address caused the test to fail.

Furthermore, obtain the page size from the system instead of hardcoding
4096.

Saleem Abdulrasool 6e6c1c3ef2 tests: correct builtins test if built under -mthumb on ARM
The clear_cache and enable_execute_stack tests attempt to memcpy the definition
of a function into a buffer before executing the function.  The problem with
this approach is that on some targets (ARM with thumb mode compilation, MIPS
with MIPS16 codegen or uMIPS), you would use a pointer which is incorrect (it
would be off-by-one) due to the ISA selection being encoded into the address.
This ensures that the function address is retrieved correctly in all cases.
