Perform more thorough checking of t2IT mask parameters, which fixes all remaining crashers when disassembling the entire 16-bit instruction space.

Hook up 64-bit atomic load/store on x86-32.  I plan to write more efficient implementations eventually.

.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

We'll need to pay attention to them when we start getting more serious about
the details of parsing thumb2 assembly.

found.  This caused LLDB to crash later in
expression parsing.

table when serializing an AST file. This was a holdover from the days
before chained PCH, and is a complete waste of time and storage
now. It's a good thing it's useless, because I have no idea how I
would have implemented MaterializeVisibleDecls efficiently in the
presence of modules.

Fix FiXME in test file. Remove FIXME for SUB (SP minus register) since that
form is Thumb2 only.

which supports both pre-order and post-order traversal via a visitor
mechanism. Use this depth-first search with a post-order traversal to
give predictable ordering semantics when walking all of the lexical
declarations in the translation unit.

Eventually, module imports will occur in the source code rather than
at the beginning, and we'll have to revisit this walk.

[analyzer] Copy GC mode setting from CFRefCount to RetainReleaseChecker in preparation for getting rid of CFRefCount.

This is a little hacky for now but will get better once we decide the best way to handle this.

[analyzer] Allow checker writes to specify that no region should be accosiated with the report. (Useful when we report an error on endOfPath or deadSymbols, when the range of the last expression might have nothing to do with the error.)

This is a very small regression (actually introduced in r138309) because it won't catch leaks of objects passed by reference to CFDictionaryCreate (they're considered to have escaped and are ignored). If this is important we can put in a specific eval::Call to restore the functionality.

module DAG-based lookup scheme. This required some reshuffling, so
that each module stores its own mapping from DeclContexts to their
lexical and visible sets for those DeclContexts (rather than one big
"chain"). 

Overall, this allows simple qualified name lookup into the translation
unit to gather results from multiple modules, with the lookup results
in module B shadowing the lookup results in module A when B imports A.

Walking all of the lexical declarations in a module DAG is still a
mess; we'll end up walking the loaded module list backwards, which
works fine for chained PCH but doesn't make sense in a DAG. I'll
tackle this issue as a separate commit.

[analyzer] Slightly clean up the fix in 138432, so that it doesn't depend on the relative ordering of path-sensitive and path-insensitive checks. Still not ideal, but I think a real fix would require infrastructure that doesn't exist yet.
