expression in IVUsers, because in the case of a use of a non-linear
addrec outside of a loop, this causes the addrec to be evaluated as
a linear addrec.

preferring to use their replacements in GRState. This further unifies the code
paths for such logic and leads to some code reduction.

Nicolas, this is probably the cause of the failures you were seeing.

as if they were multiple uses of the same instruction.  This interacts
well with the existing loadpre that j-t does to open up many new jump
threads earlier.

place it with -pedantic.  Remove -Wunused since it
is implied by -Wall.  Group -Wno-unused-parameter
with -Wall -W since it is the combination of these
two that turns on -Wunused-parameter.

because the type of the symbol is used to create the default range. We need the
sign to be consistent.

when it allows forming a tail call.  Patch by Frits van
Bommel.  This implements PR4323.

Latency information for ARM v6. It's rough and not yet hooked up. Right now  we are only using branch latency to determine if-conversion limits.

while experimenting.  I'm reasonably sure this is correct, but please 
tell me if these instructions have some strange property which makes this
change unsafe.

llvm-svn: 73746

Fix weird class-size-being-different problems.  At some level this is being caused by config.h not being
included everywhere.

implementation.  The idea is that we want asmprinting to
work by converting MachineInstrs into a new MCInst class,
then the per-instruction asmprinter works on MCInst.  MCInst
and the new asmprinters will not depend on most of the 
llvm code generators.  This allows building diassemblers
that don't link in the whole llvm code generator.  This is
step #1 of many.

into DarwinTargetAsmInfo.cpp.  The remaining differences should
be evaluated.  It seems strange that x86/arm has .zerofill but ppc
doesn't, etc.

Make changes to PCHReader to allow reading a PCH file without having a pre-initialized Preprocessor.

-Introduce 'PCHReaderListener' which is an abstract interface for getting various information from the PCHReader.
-If PCHReader is constructed without a Preprocessor, it can still load the file and invoke the callbacks of PCHReaderListener.
-If PCHReader is constructed with an initialized Preprocessor, PCHValidator is used as a PCHReaderListener to validate the contents of the PCH file against the given Preprocessor.
