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:
in aeabi_ldivmod and uldivmod, using r6 instead of r12 as the temp reg due to limitation of Thumb1 ISA.
Now, all EABI sources are Thumb1 compatible.
Also added test cases by reusing the test cases from divmodsi4_test.c, udivmodsi4_test and udivmoddi4_test.c

When building with clang/LLVM in MSVC mode, the msvcrt libraries contain
these functions.
When building in a mingw environment, we need to provide them somehow,
e.g. via compiler-rt.
The aeabi divmod functions work in the same way as the corresponding
__rt_*div* functions for windows, but their parameters are swapped.
The functions for converting float to integer and vice versa are the
same as their aeabi equivalents, only with different function names.

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.
