Fix PR26134: When substituting into default template arguments, keep
CurContext unchanged.
Or, do not set Sema's CurContext to the template declaration's when
substituting into default template arguments of said template
declaration.
If we do push the template declaration context on to Sema, and the
template declaration is at namespace scope, Sema can get confused and
try and do odr analysis when substituting into default template
arguments, even though the substitution could be occurring within a
dependent context.
I'm not sure why this was being done, perhaps there was concern that
if a default template argument referred to a previous template
parameter, it might not be found during substitution - but all
regression tests pass, and I can't craft a test that would cause it
to fails (if some one does, please inform me, and i'll craft a
different fix for the PR).
This patch removes a single line of code, but unfortunately adds more
than it removes, because of the tests. Some day I still hope to
commit a patch that removes far more lines than it adds, while
leaving clang better for it ;)
Sorry that r253590 ("Change the expression evaluation context from
Unevaluated to ConstantEvaluated while substituting into non-type
template argument defaults") caused the PR!
This fix will be merged to the upstream release_38 branch soon, but we
need it now, to fix a failure in the databases/sfcgal port.

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

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.

It controls everything that -flimit-debug-info used to, plus the

Standalone is the default on Darwin until dtrace is updated to work with
