Expose the processor resources defined by the machine model to the
scheduler and other clients through the TargetSchedule interface.
Normalize each resource count with respect to other kinds of
resources. This allows scheduling heuristics to balance resources
against other kinds of resources and latency.

Thanks to Richard Smith for pointing this out. This code stopped
serving its purpose during r103212 in a refactoring. My initial
fix was to add back the logic to abort the USR generation for
InternalLinkage, but enough tests broke suspiciously that I fear
that USR generation for cursors with InternalLinkage is now expected
by some clients (where it wasn't the case when the refactoring
took place). I don't own this code anymore and have not looked
at it for some time, but clearly this code is dead and can be removed
pending further review on the proper logic here.

disabling byval, we set realign to true.
It will perform an aligned alloca, and call memcpy to copy the byval
argument to the local variable.
Change the size threshold back to 64 bytes.

-fno-address-sanitizer, -fthread-sanitizer, -fno-thread-sanitizer, and
-fcatch-undefined-behavior as deprecated: produce a warning if they are used
pointing to the corresponding -fsanitize= option. In passing add the missing
'-' to some diagnostics.

reference instead of relying on computing it.
In general, if storage is no issue, it is preferable to deserialize info from
the PCH instead of trying to recompute it after the PCH was loaded.
The incentive to change this now was due to r155303 changing how friend template
classes in dependent contexts are handled; such classes can now be chained to
a previous template class but the computed InjectedClassNameType may be different
due to the extra template parameters from the dependent context.
The new handling requires more investigation but, in the meantime, writing out
InjectedClassNameType fixes PCH issue in rdar://12627738.

Unnamed bitfields cause struct layout problems
Synthesize unnamed bitfields when required. Most compilers don't mention unnamed bitfields in the DWARF, so we need to create them to keep clang happy with the types we create from the DWARF. 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.

token. This is important because the first token could actually be
after an #include that triggers a module import, which might use
either Sema or the AST consumer before it would have been initialized.

- 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.

it also increases the size threshold for turning on byval.
A backend fix will be attempted.

-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.
