ab3a68a7c3 Cute bug fix: when moving links from N to this, some links could have 
been missed if node *this got merged away due to recursive merging!
Also, links were not moved correctly if a node is collapsed.

dbc34a2a95 Target/X86/Printer.cpp: Add sizePtr function, and use it instead of 
" <SIZE> PTR " string when emitting assembly.

Target/X86/X86InstrInfo.def: Tidy up a bit:
 Squashed everything down to 118 chars wide, wrapping lines so that
 comment is at the same point on each line. Rename "NoImpRegs" as
 "NoIR". (most instructions have NoImpRegs twice on a line, so this
 saves 10 columns).

 Also, annotate various instructions with flags for size of memory operand.
  (MemArg16, MemArg32, MemArg64, etc.)

Target/X86/X86InstrInfo.h: Define flags for size of memory operand.
 (MemArg16, MemArg32, MemArg64, etc.)

'logical' place.

instead of by reference, since they return the modified iterator.

1e6cfa1afa On `make clean', kill the core files produced, which are of the form: 
core.### where ### is the process ID. We use core.[0-9][0-9]* to avoid killing
core.c, core.cpp, and core.h files which may be part of benchmarks.

f13126a427 This should fix the bug seen with some registers not being allocated 
correctly: skipping instructions by incorrectly incrementing the pointer.

Also adds support for building a reg-to-regclass map, and splits the function
for saving register to stack into two, one suitable for virtual registers
(which also assigns it a physical register) and one for simply storing back
physical registers.
