Evan Cheng 8b637b177c Add an option to disable codegen prepare critical edge splitting. In theory, PHI elimination is already doing all (most?) of the splitting needed. But machine-licm and machine-sink seem to miss some important optimizations when splitting is disabled.

Eric Christopher 09f757d4bc Copy over some overridden MI wrappers for ARM fast-isel. This is where 
we're adding predicates and optional defs to the MachineInstrs.

Douglas Gregor 2c8bd47a6a When the # of top-level declarations changes after reparsing a 
translation unit, refresh code-completion results because they've
probably changed. However, enforce a cooldown period between
refreshes, to avoid thrashing.

Douglas Gregor 59cab5564f Implement support for cached code completions for 
nested-name-specifiers. Also includes fixes to the generation of
nested-name-specifier result in the non-cached case; we were producing
lame results for namespaces and namespace aliases, which (1) didn't
always have nested-name-specifiers when we want them, and (2) did not
have the necessary "::" as part of the completion.

Dan Gohman 55cd6aadc9 Make dumpPassStructure be a PMDataManager abstraction, rather than 
a Pass abstraction, since that's the level it's actually used at.
Rename Pass' dumpPassStructure to dumpPass.

This eliminates an awkward use of getAsPass() to convert a PMDataManager*
into a Pass* just to permit a dumpPassStructure call.

Jim Grosbach 36d5ec383e Better handle alignment requirements for local objects in pre-regalloc frame 
mapping. Have the local block track its alignment requirement, and then
apply that when the block itself is allocated. Previously, offsets could
get adjusted in PEI to be different, relative to one another, than the
block allocation thought they would be, which defeats the point of doing
the allocation this way. Continuing rdar://8277890
