Chris Lattner 4dc4489286 Fix PR1114 and CodeGen/Generic/2007-01-15-LoadSelectCycle.ll by being
careful when folding "c ? load p : load q" that C doesn't reach either load.
If so, folding this into load (c ? p : q) will induce a cycle in the graph.

Bill Wendling e21237e59a Fix for PR1095:
LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound
inline asm expression.

Chris Lattner 479a9fc492 Fix a regression in my isIntegral patch that broke 471.omnetpp. This is
because TargetData::getTypeSize() returns the same for i1 and i8.  This fix
is not right for the full generality of bitwise types, but it fixes the
regression.

Nick Lewycky 6ce36cff3a Don't print address of ETNode. Print the DFSNumIn which uniquely identifies
the basic block and is stable across runs in gdb or valgrind.

Make Node::update handle edges which dominate and are tighter than
existing edges.

Replace makeEqual's "squeeze theorem" code. Fixes miscompilation.

Gate the calls to defToOps and opsToDef. Before this, we were getting IG
edges about values which weren't even defined in the dominated area. This
reduces the size of the IG by about half.

Chris Lattner faa060878b Run an instcombine pass after inlining but before scalarrepl. This allows
instcombine to clean up the code, which makes more code suitable for SRoA.
This helps C++ code in particular, e.g. speeding up tramp3d by 31%.

Reid Spencer 8307a54baa For PR1113:
Increment the counter after the second use, not after the first use. This
fixes PR1113.

Also, rename some classes for simplicity and to more naturally be
reminscient of LLVM 1.9. This in preparation for additional classes that
will provide a scaled down model of the LLVM 1.9 IR.

Chris Lattner 03c4953cdd rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger.
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)

Chris Lattner c0f423a452 Terminology change: drop 'integral' completely. Now we just have integer,
which includes i1.  Change the semantics of the various instructions to
support i1 where they didn't before: for example, it is now legal [though
not terribly useful, as it is the same as xor] to add two i1 values.

Reid Spencer 04a03f2075 Reorganize things a bit in preparation for rewrite. Although this looks
like a lot, its really only two changes:

1. Move stuff that should be private to .y out of the .h file.
2. Make all semantic values pointers.

This cleans up the silly destroy methods and changes them to delete. It
also moves the TypeInfo and ValueInfo classes into the .y where we can
modify them more readily because they have no clients any more.

This shouldn't result in any functional changes in llvm-upgrade.
