65b7f3af76 Improve handling of immediates by splitting 32-bit immediates into two 16-bit 
immediate operands when they will fit into the using instruction.

83fceb9481 RMW preprocessing stuff was incorrect. Grab the stuff from x86 backend and disable some tests until it will be clever enough to handle them.

68afa54033 Make changes to rev 84292 as requested by Chris Lattner. 
Most changes are cleanup, but there is 1 correctness fix:
I fixed InstCombine so that the icmp is removed only if the malloc call is removed (which requires explicit removal because the Worklist won't DCE any calls since they can have side-effects).

b5df28a151 Incorporate various suggestions Chris gave during metadata review. 
- i < getNumElements()  instead of getNumElements() > i
- Make setParent() private
- Fix use of resizeOperands
- Reset HasMetadata bit after removing all metadata attached to an instruction
- Efficient use of iterators

0739bd0ab2 Fix PR5262: when folding select into PHI, make sure all operands are available 
in the PHI's Basic Block. This uses a conservative approach, because we don't
have dominator info in instcombine.

4e4bba5c80 Add a pass to overlay pic16 data sections for function frame and automatic 
variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph 
to detect what function frames and their automatic variables can be overlaid.
Currently this builds an archive , but needs to be changed to a loadable module.

a52fce49eb make GVN work better when TD is not around: 
"In the existing code, if the load and the value to replace it with are
of different types *and* target data is available, it tries to use the
target data to coerce the replacement value to the type of the load.
Otherwise, it skips all effort to handle the type mismatch and just
feeds the wrongly-typed replacement value to replaceAllUsesWith, which
triggers an assertion.

The patch replaces it with an outer if checking for type mismatch, and
an inner if-else that checks whether target data is available and, if
not, returns false rather than trying to replace the load."

Patch by Kenneth Uildriks!
