Summary: The previous code which avoided infinite recursion (because of reparsing declarations in function parameter lists) contained SourceRange dependent code which had some problems when parameter types were coming from macros. The new solution is not using macros and therefore much safer. A couple of importer problems are fixed in redis and tmux by this fix. Various unittests are included.

Move the enum { ObjCMethodFamilyBitWidth = 4 } to the top of
the class. For some dark reason having the enum between the
bitfields breaks the packing with gcc version 7.3-win32 20180312.

The code defines __FLOAT_H and then includes the next <float.h>, which is
guarded on __FLOAT_H so it gets skipped entirely. This commit uses the header
guard __CLANG_FLOAT_H, like other headers (such as limits.h) do.

Looks like the only reason we use a unique_ptr here is so that we can
conditionally construct a LogicalErrorHandler. It's a small type, and
Optional can do the same thing with 100% fewer heap allocations.
llvm-svn: 338962
When a non-extended temporary object is created in a conditional branch, the
lifetime of that temporary ends outside the conditional (at the end of the
full-expression). If we're inserting lifetime markers, this means we could end
up generating
if (some_cond) {
lifetime.start(&tmp);
Tmp::Tmp(&tmp);
}
// ...
if (some_cond) {
lifetime.end(&tmp);
}
... for a full-expression containing a subexpression of the form `some_cond ?
Tmp().x : 0`. This patch moves the lifetime start for such a temporary out of
the conditional branch so that we don't need to generate an additional basic
block to hold the lifetime end marker.
This is disabled if we want precise lifetime markers (for asan's
stack-use-after-scope checks) or of the temporary has a non-trivial destructor
(in which case we'd generate an extra basic block anyway to hold the destructor
call).

__builtin_memmove (in non-type-punning cases).
This is intended to permit libc++ to make std::copy etc constexpr
without sacrificing the optimization that uses memcpy on
trivially-copyable types.
__builtin_strcpy and __builtin_wcscpy are not handled by this change.
They'd be straightforward to add, but we haven't encountered a need for
them just yet.
This reinstates r338455, reverted in r338602, with a fix to avoid trying
to constant-evaluate a memcpy call if either pointer operand has an
invalid designator.

Libc++ needs to know when aligned allocation is supported by clang, but is
otherwise unavailable at link time. Otherwise, libc++ will incorrectly end up
generating calls to `__builtin_operator_new`/`__builtin_operator_delete` with
alignment arguments.
This patch implements the following changes:
* The `__cpp_aligned_new` feature test macro to no longer be defined when
aligned allocation is otherwise enabled but unavailable.
* The Darwin driver no longer passes `-faligned-alloc-unavailable` when the
user manually specifies `-faligned-allocation` or `-fno-aligned-allocation`.
* Instead of a warning Clang now generates a hard error when an aligned
allocation or deallocation function is referenced but unavailable.
