The %arm_call_apsr expansion doesn't work when config.clang is a clang
driver defaulting to a non-ARM arch. Rather than fix it, replace
call_apsr.S with inline asm in call_apsr.h, which also resolves the
FIXME added in D31259.
Maybe the `__attribute__((noinline,pcs("aapcs")))` attributes are
unnecessary on the static functions, but I was unsure what liberty the
compiler had to insert instructions that modified the condition codes,
so it seemed helpful.

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.
