Remove all "cached" data from BuildVectorSDNode, preferring to retrieve
results via reference parameters.

This patch also appears to fix Evan's reported problem supplied as a
reduced bugpoint test case.

Added support to have TableGen provide information if an intrinsic (core
or target) can be overloaded or not.

If compile unit's language is not set then don't crash while dump'ing compile unit.

Extension of GEP in constant folder was broken (apparently this code
has never been run!).
 - Sorry, don't know how to make an LLVM test case for this.

Rename ScalarEvolution's getIterationCount to getBackedgeTakenCount,
to more accurately describe what it does. Expand its doxygen comment
to describe what the backedge-taken count is and how it differs
from the actual iteration count of the loop. Adjust names and
comments in associated code accordingly.

Overhaul my earlier submission due to feedback. It's a large patch, but most of
them are generic changes.

- Use the "fast" flag that's already being passed into the asm printers instead
  of shoving it into the DwarfWriter.

- Instead of calling "MI->getParent()->getParent()" for every MI, set the
  machine function when calling "runOnMachineFunction" in the asm printers.

Add a debugging option for SSC DCE.

- Use the "Fast" flag instead of "OptimizeForSize" to determine whether to emit
  a DBG_LABEL or not. We want to fall back to the original way of emitting debug
  info when we're in -O0/-fast mode.
- Add plumbing in to pass the "Fast" flag to places that need it.
- XFAIL DebugInfo/deaddebuglabel.ll. This is finding 11 labels instead of 8. I
  need to investigate still.

Fix a ValueTracking rule: RHS means operand 1, not 0. Add a simple
ashr instcombine to help expose this code. And apply the fix to
SelectionDAG's copy of this code too.

Generalize the ChangeCompareStride code, in preparation for
handling non-constant strides. No functionality change.

gdb uses DW_AT_prototyped to identify K&R style in C based languages.
This fixes objc.dg/dwarf-prototypes.m scan-assembler DW_AT_prototyped from llvmgcc42 test suite.

While folding unconditional return move DbgRegionEndInst into the predecessor, instead of removing it. This fixes following tests from llvmgcc42 testsuite.

If there is not any debug info available for any global variables and any subprograms then there is not any debug info to emit.

Back out the change in 64918 that used sign-extensions when promoting
trip counts that use signed comparisons. It's not obviously the best
approach for preserving trip count information, and at any rate there
isn't anything in the tree right now that makes use of that, so for
now always using zero-extensions is preferable.

Fast-isel can't do TLS yet, so it should fall back to SDISel
if it sees TLS addresses.

Correctly implement ImmutableMap::getMaxElement() by getting the actual <key, value> pair.
