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.

Summary:
The `b` instruction in Thumb1 has limited range, which may cause link-time errors if the jump target is far away.
This patch guards the tailcalls for non-Thumb1

Summary:
Align __aeabi_memclr to 4 bytes. All other ARM functions are already aligned to
4-bytes in compiler-rt.

syntax fix
Summary:
Make the asm of aeabi_memset be assembled for thumb1.
Also fix some instructions to conform with the syntax of ARM reference manual.
For example, muls requires the form of "Rd, Rn, Rd" and orrs requires
the form of "Rd, Rm". Clang-as is benign but it may fail other assembler
if not in the exact form.

Use unified syntax for builtins/arm/aeabi_mem*.S.
This makes these files consistent with the others.
This fixes a problem on the linker, which can fail with the message
"relocation truncated to fit: R_ARM_THM_JUMP11 against symbol"

These routines do not require executable stacks. However, by default ELFish
linkers may assume an executable stack on GNUish environments (and some non-GNU
ones too!). The GNU extension to add a note to indicate a non-executable stack
is honoured by these environments to mark the stack as non-executable (the
compiler normally emits this directive on appropriate targets whenever
possible). This allows normal builds from getting executable stacks due to
linking to the compiler rt builtins.

The .align statements in ARM assembly routines is actually meant to be a power
of 2 alignment (e.g. .align 2 == 4 byte alignment, not 2). Switch to using
.p2align. .p2align is guaranteed to be a power-of-two alignment always and much
more explicit.
The .align in the case of x86_64 is byte alignment, use .balign instead of
.align.
