dff0a891c1 Major improvement to how nodes are built for a BB. 
LLVM instruction is no longer recorded in each node, but BB is.

computing size of extra outgoing args.

6cd83556e6 Only add true dep. edges from an earlier to a later instruction. 
This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!

31305c0d57 Coalesing bug fix - now checks for the same regType instead of the same 
regClass since FP class has two reg Types.

Much nicer.

621b90440b Major change to how defs are found when adding dependences (they 
are now found as part of the initial walk of the machine code).
Also memory load/store instructions can be generated for non-memory
LLVM instructions, which wasn't handled before.  It is now.

is already pushed to stack by a previous call to the same method.

with instr. selection.

df6913549a Add edges between call instructions and (a) load/store instructions, and 
(b) any instructions that use or set CC registers.  Whether or not the
latter are needed really should be machine-dependent.

6d19dc9080 1. Add a bottom-up pass on BURG trees that is used to fix constant operands. 
Needs to be bottom up because constant values may be forward-substituted
   to their uses (i.e., into the parent in the BURG tree).
2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.
