Daniel Dunbar 529c03bc1e Driver: Sketch driver support for a CC_LOG_DIAGNOSTICS options, similar to the 
existing CC_PRINT_OPTIONS and CC_PRINT_HEADERS, which can be used to
transparently capture the compiler diagnostics from a build.

Stephen Wilson f6e259049d Removed use of NSEC_PER_SEC. 
NSEC_PER_SEC is not defined in sys/time.h on Linux. Replaced that macro with a
static constant inside TimeValue.

Stephen Wilson 0682ba2f2e linux: remove ProcessLinux::FindProcesses 
This method only needs to be overridden in the remote debugging case,  the
base class handles the host case.  Since we do not do remote debugging on
Linux yet and there is a typo that causes a build issue, just remove this
method for now.

John McCall 319963434c Basic, untested implementation for an "unknown any" type requested by LLDB. 
The idea is that you can create a VarDecl with an unknown type, or a
FunctionDecl with an unknown return type, and it will still be valid to
access that object as long as you explicitly cast it at every use.  I'm
still going back and forth about how I want to test this effectively, but
I wanted to go ahead and provide a skeletal implementation for the LLDB
folks' benefit and because it also improves some diagnostic goodness for
placeholder expressions.

Eli Friedman c5f22a7815 PR9634: Don't unconditionally tell the AliasSetTracker that the PreheaderLoad 
is equivalent to any other relevant value; it isn't true in general.
If it is equivalent, the LoopPromoter will tell the AST the equivalence.
Also, delete the PreheaderLoad if it is unused.

Chris, since you were the last one to make major changes here, can you check
that this is sane?

The ARM disassembler should reject invalid (type, align) encodings as invalid instructions.

So, instead of:

	vst2.32	{d0, d2}, [r3, :256], r3

we now have:

Johnny Chen 2ac486e387 A8.6.92 MCR (Encoding A1): if coproc == '101x' then SEE "Advanced SIMD and VFP" 
Since these "Advanced SIMD and VFP" instructions have more specfic encoding bits
specified, if coproc == 10 or 11, we should reject the insn as invalid.
