[builtins] Support architectures with 16-bit int
This is the first patch in a series to add support for the AVR target.
This patch includes changes to make compiler-rt more target independent
by not relying on the width of an int or long.

Petr Hosek 082b89b25f [builtins] Reformat builtins with clang-format
Update formatting to use the LLVM style.

This is part of the cleanup proposed in "[RFC] compiler-rt builtins
cleanup and refactoring".

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.

Saleem Abdulrasool 911cfc11c4 builtins: spell inline as __inline
__inline is a vendor specific spelling for inline.  clang and gcc treat it the
same as inline, and is available in MSVC 2013 which does not implement C99
(VS2015 supports the inline keyword though).  This will allow us to build the
builtins using MSVC.

Ahmed Bougacha f1ac850e77 [Builtins] Implement half-precision conversions.
Mostly uninteresting, except:
- in __extendXfYf2, when checking if the number is normal, the old
  code relied on the unsignedness of src_rep_t, which is a problem
  when sizeof(src_rep_t) < sizeof(int): the result gets promoted to
  int, the signedness of which breaks the comparison.
  I added an explicit cast; it shouldn't affect other types.
- we can't pass __fp16, so src_t and src_rep_t are the same.
- the gnu_*_ieee symbols are simply duplicated definitions, as aliases
  are problematic on mach-o (where only weak aliases are supported;
  that's not what we want).
