Apparently __builtin_abort() is not supported when targetting Windows.
This should fix the following builder errors:
clang_rt.builtins-x86_64.lib(int_util.c.obj) : error LNK2019: unresolved
external symbol __builtin_abort referenced in function __compilerrt_abort_impl
When compiled with -ffreestanding, we should not assume that headers
declaring functions such as abort() are available. While the compiler may
still emit calls to those functions [1], we should not require the headers
to build compiler-rt since that can result in a cyclic dependency graph:
The compiler-rt functions might be required to build libc.so, but the libc
headers such as stdlib.h might only be available once libc has been built.
[1] From https://gcc.gnu.org/onlinedocs/gcc/Standards.html:
GCC requires the freestanding environment provide memcpy, memmove,
memset and memcmp. Finally, if __builtin_trap is used, and the target
does not implement the trap pattern, then GCC emits a call to abort.

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.

Add Fuchsia support to some builtings and avoid building builtins
that are not and will never be used on Fuchsia.

Unfortunately, int_utils.h needs to depend on int_lib for the common macro
definitions. However, currently, int_utils.h is included by int_lib.h. Reorder
the inclusion to work around this.
