Update the intel intrinsic headers to use the target attribute support.
This involved removing the conditional inclusion and replacing them
with target attributes matching the original conditional inclusion
and checks. The testcase update removes the macro checks for each
file and replaces them with usage of the __target__ attribute, e.g.:
int __attribute__((__target__(("sse3")))) foo(int a) {
_mm_mwait(0, 0);
return 4;
}
This usage does require the enclosing function have the requisite
__target__ attribute for inlining and code generation - also for
any macro intrinsic uses in the enclosing function. There's no change
for existing uses of the intrinsic headers.

Remove `requires` for x86 CPU features.
Ever since the target attributes change, we don't need to guard these
headers with `requires`. Actually it's a bit worse, because if we do
then they are included textually under the covers, causing declarations
to appear in submodules they aren't supposed to be in.
------------------------------------------------------------------------
This reverts the changes to the intrinsics headers in trunk, which could
result in some ports' configure scripts misdetecting SSE (and higher)
support.

Fix assert instantiating string init of static variable
... when the variable's type is a typedef of a ConstantArrayType. Just
look through the typedef (and any other sugar). We only use the
constant array type here to get the element count.
This fixes an assertion failure when building the games/redeclipse port.

These are generated, and not "optimized" in any way, since I am not
entirely sure of the syntax or format of this type of file. Feel free
to suggest ways of shortening these lists.
The general idea is the same for all three files, though:
* Get rid of upstream build infrastructure (CMakeLists, Makefiles, etc)
* Delete tests, tools and utilities we don't want or use (including
samples)
* Remove various bits of upstream metadata files that we don't want or
use (.arcconfig, .gitignore, etc)
FreeBSD core files have no section table and thus LLDB's OS and vendor
detection logic does not work. If we encounter such an ELF file, update
an unknown OS to match the host.
This is not really the correct way to handle this, but more extensive
rework of ObjectFileELF will be needed and this change restores cross-
arch core debugging until that can be completed.
There's an unfortunate layering issue between LLDB's Process/POSIX and
Process/{FreeBSD,Linux}, exposed by a refactoring in upstream revision
218568. Work around it by adding explicit #if defined(__FreeBSD__)
guards to include the correct header.
Allows Clang to use LLVM's fixes-x18 option
This patch allows clang to have llvm reserve the x18
platform register on AArch64. FreeBSD will use this in the kernel for
per-cpu data but has no need to reserve this register in userland so
will need this flag to reserve it.
This uses llvm r226664 to allow this register to be reserved.

This only allows testing and does not change the defaults for mips/mips64.
They still build/use gcc by default.

PR20228: don't retain a pointer to a vector element after the
container has been resized.
This fixes a possible crash when compiling certain parts of libc++'s
type_traits header.
Implement vaarg lowering for ppc32. Lowering of scalars and
aggregates is supported. Complex numbers are not.
This adds va_args support for PowerPC (32 bit) to clang.
