cc6543cb51 Making an archive version of the CodeGen library is unnecessary if we just
move InstructionLowering itself.

IntrinsicLowering, for instance).

aebcce8404 Fix a recent regression in Applications/sgefa that Alkis pointed out to me.
The vector may actually be empty if the register that we are marking as
recently used is not actually allocatable.  This happens for physical registers
that are not allocatable, like the ST(x) registers on X86.

137cc4fc8c I misled Alkis: LLVM should have isnan, not isunordered.
isunordered(X, Y) === isnan(X) | isnan(Y)

bee887211b Fix a really nasty bug from my changes on Monday to PHIElim. These changes
broke obsequi and a lot of other things.  It all boiled down to MBB being
overloaded in an inner scope and me confusing it with the one in the outer
scope.  Ugh!

0bcb1ad7be Add non-const MachineBasicBlock::getParent() accessor method.
MBBs start out as #-1. When a MBB is added to a MachineFunction, it
gets the next available unique MBB number. If it is removed from a
MachineFunction, it goes back to being #-1.

80e20eb487 Use a new VRegPHIUseCount to compute uses of PHI values by other phi values
in the basic block being processed.  This fixes PhiElimination on kimwitu++
from taking 105s to taking a much more reasonable 0.6s (in a debug build).

791f896d9f Now that we use an ilist of machine instructions, iterators are more robust
than before.  Because this is the case, we can compute the first non-phi
instruction once when de-phi'ing a block.  This shaves ~4s off of
phielimination of _Z7yyparsev in kimwitu++ from 109s -> 105s.  There are
still much more important gains to come.

6d3848df7e Patch to fix PR337. Make sure to mark all aliased physical registers as used
when we see a read of a register.  This is important in cases like:

AL = ...
AH = ...

   = AX

The read of AX must make both the AL and AH defs live until the use.
