The class seems to have an invariant that Entries is non-empty if
Invalid is false. It appears this method was previously private, and
all internal uses checked Invalid. Now there is an external caller, so
check Invalid to avoid array OOB underflow.
Fixes PR20420.

The main subtlety here is that the Darwin tools still need to be given "-arch
arm64" rather than "-arch aarch64". Fortunately this already goes via a custom
function to handle weird edge-cases in other architectures, and it tested.
I removed a few arm64_be tests because that really isn't an interesting thing
to worry about. No-one using big-endian is also referring to the target as
arm64 (at least as far as toolchains go). Mostly they date from when arm64 was
a separate target and we *did* need a parallel name simply to test it at all.
Now aarch64_be is sufficient.

parameter, put the name of the parameter in the middle of the type, not at the
end.

This field is never inspected in the object state initialized by this
constructor; however, initializing it seems reasonable, since it has
a meaningful value.

C99 array parameters can have index-type CVR qualifiers, and the TypePrinter
should print them when present (and we were not for constant-sized arrays).
Otherwise, we'd drop the restrict in:
int foo(int a[restrict static 3]) { ... }

Assigns indices to try blocks. These indices will used in constructing
tables that the mscrt function __except_handler3 reads during SEH.
Testing will occur once we actually emit the tables, in a subsequent
patch.

In C99, an array parameter declarator might have the form: direct-declarator
'[' 'static' type-qual-list[opt] assign-expr ']'
and when the size of the array is a constant, don't omit the static keyword
when printing the type. Also, in the VLA case, put a space after the static
keyword (some assignment expression must follow it).

This makes us emit dllexported in-class initialized static data members (which
are treated as definitions in MSVC), even when they're not referenced.
It also makes their special linkage reflected in the GVA linkage instead of
getting massaged in CodeGen.

This is a follow-up to an IRC conversation with Richard last night; __assume
does not evaluate its argument, and so the argument should not contribute to
whether (__assume(e), constant) can be used where a constant is required.

-- a constructor list initialization that unpacked an initializer list into
constructor arguments and
-- a list initialization that created as std::initializer_list and passed it
as the first argument to a constructor
in the AST. Use this flag while instantiating templates to provide the right
semantics for the resulting initialization.

We would correctly insert sufficiently aligned padding between vbases
when our leading base was empty, however we would neglect to increase
the required alignment of the most derived class.
This fixes PR20315.

No functionality changed, just some cleanups:
- Switch some loops to range-based for.
- Name some iterators with a more creative name than "I".
- Reduce dependence on auto. Does RD->bases() give you a list of
CXXBaseSpecifiers or CXXRecordDecls? It's more clear to just say which
upfront.

While we previously supported __uuidof applied to a template
specialization, we would only find the uuid attribute if it was applied
to the template argument. We would erroneously ignore the uuid
attribute on the specialization itself.
This is required to parse Windows Runtime C++ Template Library headers.

Switch some things to use range-based for loops.
Change CXXUuidofExpr::GetUuidAttrOfType's return type to be const.
