[analyzer] Refactor: make PathDiagnosticLocation responsible for validation of SourceLocations (commit 2 of ?):
- Fix a fixme and move the logic of creating a PathDiagnosticLocation corresponding to a ProgramPoint into a PathDiagnosticLocation constructor.
- Rename PathDiagnosticLocation::create to differentiate from the added constructor.

When we load the first module, make sure that we wire up the ASTConsumer to the newly-created ASTReader. This makes sure that CodeGen sees the declarations it is interested in

The the MC disassembler C API to print in verbose mode.  Perhaps there should be a parameter to request verbose mode?

Add support for stored annotations to MCInst, and provide facilities for MC-based InstPrinters to print them out.  Enhance the ARM and X86 InstPrinter's to do so in verbose mode.

Fix the stats counters to reflect that.

take into consideration the presence of AVX. This change, together with
the SSEDomainFix enabled for AVX, makes AVX codegen to always (hopefully)
emit the same code as SSE for 128-bit vector ops. I don't
have a testcase for this, but AVX now beats SSE in performance for
128-bit ops in the majority of programas in the llvm testsuite

The number of spills could go negative since a folded COPY is just a
spill, and it may be eliminated.

-Use an array of offsets for all preprocessed entities
-Get rid of the separate array of offsets for just macro definitions;
 for references to macro definitions use an index inside the preprocessed
 entities array.
-Deserialize each preprocessed entity lazily, at first request; not in bulk.

Paves the way for binary searching of preprocessed entities that will offer
efficiency and will simplify things on the libclang side a lot.

Assembler private local symbols aren't legal targets of symbol attributes,
so issue a diagnostic for them.

If we see an EOF w/o a preceding end-of-line, return an EndOfStatement

When traceSiblingValue() encounters a PHI-def value created by live
range splitting, don't look at all the predecessor blocks.  That can be
very expensive in a complicated CFG.

Instead, consider that all the non-PHI defs jointly dominate all the
PHI-defs.  Tracing directly to all the non-PHI defs is much faster that
zipping around in the CFG when there are many PHIs with many
predecessors.

This significantly improves compile time for indirectbr interpreters.

The getPrevIndex() function moves to the same slot in the previous
instruction.  For getVNInfoBefore(), we just need the previous slot in
the same instruction.

Blocks with multiple PHI successors only need to go on the worklist
once.  Use a SmallPtrSet to track the live-out blocks that have already
been handled.  This is a lot faster than the two live range check we
would otherwise do.

Also stop recomputing hasPHIKill flags.  Like RenumberValues(), it is
conservatively correct to leave them in, and they are not used for
anything important.

possible for that to matter right now, but eventually I think we'll
need to unify this better, and then it might.  Also, use a more
efficient looping structure.

It does, after all.

RemoveCopyByCommutingDef rewrites the uses of one particular value
number in A. It doesn't know how to rewrite phi uses, so there can't be
any.

from documented values to reality.
