Benjamin Kramer bb09cb6433 Simplify PDiag's move assignment overload a bit, the self-move check isn't actually necessary. 
This just empties out the diag, which is fine.

Argyrios Kyrtzidis 8b71bc7d6b [libclang] Introduce a new indexing mode where we skip function bodies 
that were already parsed in the same "indexing session".

An indexing session is defined as using the same CXIndexAction object
for multiple clang_indexSourceFile calls.
Passing CXIndexOpt_SkipParsedBodiesInSession as an indexing option will
enable the mode where we try to skip bodies that were already parsed in
another translation unit.

If a function's body was skipped, the "flags" field in the CXIdxDeclInfo
structure will have "CXIdxDeclFlag_Skipped" bit was set.

Evan Cheng 9ec512d768 Replace r169459 with something safer. Rather than having computeMaskedBits to 
understand target implementation of any_extend / extload, just generate
zero_extend in place of any_extend for liveouts when the target knows the
zero_extend will be implicit (e.g. ARM ldrb / ldrh) or folded (e.g. x86 movz).

Jordan Rose 9163978b2c Allow modifying an ImmutableMap without canonicalizing it immediately. 
This is an alternative to the ImmutableMapRef interface where a factory
should still be canonicalizing by default, but in certain cases an
improvement can be made by delaying the canonicalization.

Argyrios Kyrtzidis 1eb71a1ba7 Add a bit on FunctionDecl/ObjCMethodDecl to indicate if there was a body 
that was skipped by the parser.

Jordan Rose ff03c1d26d [analyzer] Simplify RetainCountChecker's handling of dead symbols. 
Previously we made three passes over the set of dead symbols, and removed
them from the state /twice/. Now we combine the autorelease pass and the
symbol death pass, and only have to remove the bindings for the symbols
that leaked.

Jordan Rose 5e4e61ddf9 [analyzer] Use a smarter algorithm to find the last block in an inlined call. 
Previously we would search for the last statement, then back up to the
entrance of the block that contained that statement. Now, while we're
scanning for the statement, we just keep track of which blocks are being
exited (in reverse order).

Jordan Rose a64c6dbb98 [analyzer] Speed up ExplodedNode::Profile by avoiding copy constructors.

Jordan Rose 1ecba4cc69 [analyzer] Use optimized assumeDual for branches. 
This doesn't seem to make much of a difference in practice, but it does
have the potential to avoid a trip through the constraint manager.

Jordan Rose 5f28afc8a1 [analyzer] Aggressively cut back on the canonicalization in RegionStore. 
Whenever we touch a single bindings cluster multiple times, we can delay
canonicalizing it until the final access. This has some interesting
implications, in particular that we shouldn't remove an /empty/ cluster
from the top-level map until canonicalization.

This is good for a 2% speedup or so on the test case in
<rdar://problem/12810842>

Jordan Rose 047208027a [analyzer] Remove bindExprAndLocation, which does extra work for no gain. 
This feature was probably intended to improve diagnostics, but was currently
only used when dumping the Environment. It shows what location a given value
was loaded from, e.g. when evaluating an LValueToRValue cast.
