Dan Gohman 6d919f1613 Simplify this code; it's not necessary to check isIdentifiedObject here 
because if the results from getUnderlyingObject match, the values must
be from the same underlying object, even if we don't know what that
object is.

Douglas Gregor ee9067c51f When we have a non-dependent expression such as 
A::f

that occurs within a non-static member function with a type-dependent
"this", don't consider this to be a case for introduction of an
implicit "(*this)." to refer to a specific member function unless we
know (at template definition time) that A is a base class of *this.

There is some disagreement here between GCC, EDG, and Clang about the
handling of this case. I believe that Clang now has the correct,
literal interpretation of the standard, but have asked for
clarification (c++std-core-15483).

Dan Gohman 91449224e8 Refine the capture tracking rules for comparisons to be more 
careful about crazy methods of capturing pointers using comparisons.
Comparisons of identified objects with null in the default address
space are not captures. And, comparisons of two pointers within the
same identified object are not captures.

Jim Grosbach b73918c42d When placing constant islands and adjusting for alignment padding, inline 
assembly can confuse things utterly, as it's assumed that instructions in
inline assembly are 4 bytes wide. For Thumb mode, that's often not true,
so the calculations for when alignment padding will be present get thrown off,
ultimately leading to out of range constant pool entry references. Making
more conservative assumptions that padding may be necessary when inline asm
is present avoids this situation.

John McCall 8cd7813ca3 Draw a brighter line between "unresolved" expressions, where we have done the 
appropriate lookup and simply can't resolve the referrent yet, and
"dependent scope" expressions, where we can't do the lookup yet because the
entity we need to look into is a dependent type.

Dan Gohman 94e617627d Extend CaptureTracking to indicate when a value is never stored, even 
if it is not ultimately captured. Teach BasicAliasAnalysis that a 
local object address which does not escape and is never stored does
not alias with a value resulting from a load.

Jakob Stoklund Olesen 331e6880a5 Place new basic blocks immediately after their predecessor when splitting 
critical edges in PHIElimination.

This has a huge impact on regalloc performance, and we recover almost all of
the 10% compile time regression that edge splitting introduced.

Johnny Chen b3b8209d77 Added NLdStLN which is similar to NLdSt with the exception that op7_4 is not 
fully specified at this level.  Subclasses of NLdStLN can specify selective
bit(s) for Inst{7-4}, as is done for VLD[234]LN* and VST[234]LN* inside
ARMInstrNEON.td.
