They identify the PHI predecessors in both diamonds and triangles.

When a trace ends with a back-edge, include PHIs in the loop header in
the height computations. This makes the critical path through a loop
more accurate by including the latencies of the last instructions in the
loop.

- if a boolean test (X86ISD::CMP or X86ISD:SUB) checks a boolean value
  generated from X86ISD::SETCC, try to simplify the boolean value
  generation and checking by reusing the original EFLAGS with proper
  condition code
- add hooks to X86 specific SETCC/BRCOND/CMOV, the major 3 places
  consuming EFLAGS

Instead of adding it to each individual subclass in
Targets.cpp, simply check the appropriate target
values.

Where before it was only on x86_64 and ppc64, it's now
also defined on mips64 and nvptx64.

Also add a bunch of negative tests to ensure it is *not*
defined on any other architectures while we're here.

TODO:
 - Handle @syncronized properties.
 - Always inline properties declared publicly (do not split the path).
This is tricky since there is no mapping from a Decl to the property in
the AST as far as I can tell.

llvm-svn: 161683

When object is allocated with alloc or init, we assume it cannot be a
subclass (currently used only for bifurcation purposes).

llvm-svn: 161682

when we don't need to split.

In some cases we know that a method cannot have a different
implementation in a subclass:
 - the class is declared in the main file (private)
 - all the method declarations (including the ones coming from super
classes) are in the main file.

This can be improved further, but might be enough for the heuristic.
(When we are too aggressive splitting the state, efficiency suffers.
When we fail to split the state coverage might suffer.)

When replacing Old with New, it can happen that New is already a
successor. Add the old and new edge weights instead of creating a
duplicate edge.

things going on here that were problematic:
  - We were missing the actual access check, or rather, it was suppressed
    on account of being a redeclaration lookup.
  - The access check would naturally happen during delay, which isn't
    appropriate in this case.
  - We weren't actually emitting dependent diagnostics associated with
    class templates, which was unfortunate.
  - Access was being propagated incorrectly for friend method declarations
    that couldn't be matched at parse-time.

switched from a bytecode+bzip2 to the current bitcode.

The old behavior was to re-scan any files (like modules) where we may have
directives but won't actually be parsing during the -verify invocation.
Now, we keep the old behavior in Debug builds as a sanity check (though
modules are a known entity), and expect all legitimate directives to come
from comments seen by the preprocessor.

This also affects the ARC migration tool, which captures diagnostics in
order to filter some out. This change adds an explicit cleanup to
CaptureDiagnosticsConsumer in order to let its sub-consumer handle the
real end of diagnostics.

This was originally split into four patches, but the tests do not run
cleanly without all four, so I've combined them into one commit.
