Roman Divacky 41e6cebb40 Use the IDVal directly as there's no need to convert to std::string.

Johnny Chen bdc5c27894 Fix the test driver as part of the fix for http://llvm.org/bugs/show_bug.cgi?id=8493 
File name "2010-10-19-14:10:49.059609" is non-portable.

Do not use ':' in the pathname as it is not permitted on windows platforms.

Douglas Gregor 16896c45f3 Simplify ASTUnit's internal timers, by not trying to keep a pile of 
timers to be dumped whenever the ASTUnit is destroyed. Instead, just
print the time elapsed for each operation after we perform the
operation.

Argyrios Kyrtzidis d9f526fc2e Switch case IDs conflict between chained PCHs; since there is no need to be global, make them local to a decl.

John McCall 9de9160d55 Implement an indirect-goto optimization for goto *&&lbl and respect this 
in the scope checker.  With that done, turn an indirect goto into a
protected scope into a hard error;  otherwise IR generation has to start
worrying about declarations not dominating their scopes, as exemplified
in PR8473.

If this really affects anyone, I can probably adjust this to only hard-error
on possible indirect gotos into VLA scopes rather than arbitrary scopes.
But we'll see how people cope with the aggressive change on the marginal
feature.

first one if the redeclaration comes from a friend decl.

Argyrios Kyrtzidis 01c2df45ff Use the ASTMutationListener to track when a named decl gets added to a DeclContext, 
meaning we need to rewrite its name lookup table in a chained PCH.

I'll work with Jim, Owen, and Bill on an alternative testing strategy until
the assembly parser is available.

*BSD(s) have environ(7) in CRT startup and cannot resolve "environ" at linking llvm.so.
environ(7) is used inlib/System/Unix/Program.inc.

John McCall 071df46743 Implement the newest status quo for method override checking. The idea now 
is that we need more information to decide the exact conditions for whether
one ObjCObjectPointer is an acceptable return/parameter override for another,
so we're going to disable that entire class of warning for now.  The
"forward developement" warning category, -Wmethod-signatures, can receive
unrestricted feature work, and when we're happy with how it acts, we'll
turn it on by default.

This is a pretty conservative change, and nobody's totally content with it.

Chris Lattner 15597538ae clarify that not having the ".o file writing" feature

Evan Cheng ff1c862f8e - Assign load / store with shifter op address modes the right itinerary classes. 
- For now, loads of [r, r] addressing mode is the same as the
  [r, r lsl/lsr/asr #] variants. ARMBaseInstrInfo::getOperandLatency() should
  identify the former case and reduce the output latency by 1.
- Also identify [r, r << 2] case. This special form of shifter addressing mode
  is "free".

Evan Cheng 59bbc545e0 Shifter ops are not always free. Do not fold them (especially to form 
complex load / store addressing mode) when they have higher cost and
