tsan: slightly relax requirements for lazy shadow memory (can overlap and may not be properly aligned)
it's problematic on windows where allocation granularity is much larger than page size

Follow-up for r167411 to un-break ASan on Mac. Move SanitizerArgs to a header file and use it on Darwin toolchain.

The file uses namespaces and extern "LANG", so it's kinda senseless to use #ifdef __cplusplus

__declspec is not _WIN32, it's _MSC_VER

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.

This is in preparation for adding "weak" DAG edges, but generally
simplifies the design.

it's also setup as 'INTERNAL_TOOL'.

-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.
