Added a README.LLVM file to indicate which files and directories
were removed from the original source tarball.

to work out (in a very simplistic way) which function
arguments (pointer arguments only) are only dereferenced
and so do not escape.  Mark such arguments 'nocapture'.

  This makes some 64-bit operations legal.

- Eliminate target-dependent ISD enums.

- Update tests.

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.

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

- Move v4i32, i32 mul into SPUInstrInfo.td, with a few more instruction
  cleanups there as well.
- Make SMUL_LOHI, UMUL_LOHI competely illegal for Cell SPU, to better
  assist Chris to see the problem in bug 3101.
