[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 84da0e1bb7 [builtins] Use aliases for function redirects
Symbol aliases are supported by all platforms that compiler-rt builtins
target, and we can use these instead of function redirects to avoid the
extra indirection.

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.

Eli Friedman 0d586d06a7 [compiler-rt] Add back ARM EABI aliases where legal.
r303188 removed all the uses of aliases for EABI functions from
compiler-rt, because some of them had mismatched calling conventions.
Obviously, we can't use aliases for functions which don't have the same
calling convention, but that's only an issue for floating-point
functions with the hardfloat ABI.  In other cases, the stubs increase
size and reduce performance for no benefit.

This patch adds back the aliases, with appropriate checks to make sure
they're only used in cases where the calling convention matches.

Saleem Abdulrasool 36ac5ddff7 builtins: expand out the AEABI function stubs
These actually may change calling conventions.  We cannot simply provide
function aliases as the aliased function may have a different calling
convention.  Provide a forwarding function instead to permit the
compiler to synthesize the calling convention adjustment thunk.

Remove the `ARM_EABI_FNALIAS` macro as that is not safe to use.

Resolves PR33030!
