02d711b93e - Start moving target-dependent nodes that could be represented by an 
instruction sequence and cannot ordinarily be simplified by DAGcombine
  into the various target description files or SPUDAGToDAGISel.cpp.

  This makes some 64-bit operations legal.

- Eliminate target-dependent ISD enums.

- Update tests.

998dee96d3 Linux wants the FDE initial location and address range to be forced to 32-bit. 
Darwin doesn't. Make this optional for platforms.

bce452815c The FDE initial location and address range data should be free to be 64-bit 
(quad) on a 64-bit platform. This fixes a problem with EH frames on Darwin.

2964fe37ae Experiments show that looking through phi nodes 
and select instructions doesn't buy anything here
except extra complexity: the only difference in
the entire testsuite was that a readonly function
became readnone in MiBench/consumer-typeset.  Add
a comment about this.

516ec62bfe Allow readnone functions to read (and write!) global 
constants, since doing so is irrelevant for aliasing
purposes.  While this doesn't increase the total number
of functions marked readonly or readnone in MultiSource/
Applications (3089), it does result in 12 functions being
marked readnone rather than readonly.
Before:
  readnone: 820
  readonly: 2269
After:
  readnone: 832
  readonly: 2257

  assist Chris to see the problem in bug 3101.

f0569be4a9 - Remove Tilmann's custom truncate lowering: it completely hosed over 
DAGcombine's ability to find reasons to remove truncates when they were not
  needed. Consequently, the CellSPU backend would produce correct, but _really
  slow and horrible_, code.

  Replaced with instruction sequences that do the equivalent truncation in
  SPUInstrInfo.td.

- Re-examine how unaligned loads and stores work. Generated unaligned
  load code has been tested on the CellSPU hardware; see the i32operations.c
  and i64operations.c in CodeGen/CellSPU/useful-harnesses.  (While they may be
  toy test code, it does prove that some real world code does compile
  correctly.)

- Fix truncating stores in bug 3193 (note: unpack_df.ll will still make llc
  fault because i64 ult is not yet implemented.)

- Added i64 eq and neq for setcc and select/setcc; started new instruction
  information file for them in SPU64InstrInfo.td. Additional i64 operations
  should be added to this file and not to SPUInstrInfo.td.
