We currently can't do this for ObjC since the DW_AT_bit_offset value for any direct ivars of ObjC classes as the values for these attributes are bogus. A bug has been filed on Clang to fix this, and another bug has been filed on LLDB to make sure we fix the DWARF parser once the clang fix is in by looking the the DW_AT_producer in the compile unit attributes and finding the compiler version and only enabling it for newer versions of clang.

Split the instrinsic header wmmintrin.h into AES and PCLMUL parts, so
that we can model them as separate submodules.

Frontend: Add support for reading named pipes as the main file.
- The whole {File,Source}Manager is built around wanting to pre-determine the
size of files, so we can't fit this in naturally. Instead, we handle it like
we do STDIN, where we just replace the main file contents upfront.

Use Richard's BE_THE_HEADER trick to simplify a test. No intended behavior change.

ARM byval: when type alignment is bigger than ABI alignment, we can't guarantee
the type alignment of the byval argument. This patch will disable byval in this case,
it also increases the size threshold for turning on byval.
A backend fix will be attempted.

Use the individual -fsanitize=<...> arguments to control which of the UBSan
checks to enable. Remove frontend support for -fcatch-undefined-behavior,
-faddress-sanitizer and -fthread-sanitizer now that they don't do anything.

Add -fsanitize=<sanitizers> argument to driver and frontend, and add
-fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the
various UBSan checks to be enabled and disabled separately. Right now, the
different modes can't be combined, but the intention is that combining UBSan
and the other sanitizers will be permitted in the near future.
Currently, the UBSan checks will all be enabled if any of them is; that will be
fixed by the next patch.
