Andrew Trick f11344d770 Check TRI->getReservedRegs because other allocators do it. Even though 
it makes no sense for allocation_order iterators to visit reserved regs.
The inline spiller depends on AliasAnalysis.
Manage the Query state to avoid uninitialized or stale results.

Ted Kremenek c7a5bae597 Annotate tokens in a separate thread to avoid blowing out stack space. While the CursorVisitor 
is gradually becoming more data recursive, AnnotateTokensVisitor does its own recursive call
within the visitor that can still blow out the stack.  This can potentially be reworked to avoid this,
but for now just do token annotation on a separate thread.

Ted Kremenek 92209a45b9 Generalize data-recursive visitation in CursorVisitor to also handle MemberExprs 
and CXXCallMemberExprs.  This scheme is hopefully general enough to extend to the
rest of the visitor if necessary.

Greg Clayton a63012e9bf Fixed an issue where we might not be able to track down a real definition of 
a forward declaration to a struct and hangle it gracefully (don't crash
trying to ask clang how many children an empty record has).

Douglas Gregor 44c6ee7729 Improve ASTUnit's capture of diagnostics so that the 
diagnostic-capturing client lives as long as the ASTUnit itself
does. Otherwise, we can end up with crashes when we get a diagnostic
outside of parsing/code completion. The circumstances under which this
happen are really hard to reproduce, because a file needs to change
from under us.

Jakob Stoklund Olesen c400670bf1 Insert two blank SlotIndexes between basic blocks instead of just one. 
This is the first small step towards using closed intervals for liveness instead
of the half-open intervals we're using now.

We want to be able to distinguish between a SlotIndex that represents a variable
being live-out of a basic block, and an index representing a variable live-in to
its successor.

That requires two separate indexes between blocks. One for live-outs and one for
live-ins.

With this change, getMBBEndIdx(MBB).getPrevSlot() becomes stable so it stays
greater than any instructions inserted at the end of MBB.
