Improved pretty-printing of LValues.
Parameters whose values are pointers/references are now assigned SymbolicLValues.

Hack Sema::MergeTypeDefDecl() to silently ignore duplicate typedef's in system headers files.

A bizarre, non-standard hook that many compilers appear to implement (sigh:-).

pretty-print a block's terminator.

When building CFGs, for IfStmts ('if'), we no longer add the ParenExpr
that is the subexpression of the IfStmt to the CFG; instead we add its
first descendant subexpression that is not a ParenExpr.

Fixed a bug in MergeValueInAsValue() pointed out by David Greene. Replace val# with previous liverange's.

On an unexpected @foo keyword, return failure instead of a 'successful' null AST.  This fixes a segfault
on things like @foo.

Treat the label for the first @llvm.dbg.stoppoint the same way as the dbg_func_start label. Make sure nothing else is inserted before them.
Note this solution might be somewhat fragile since ISD::LABEL may be used for other
purposes. If that ends up to be an issue, we may need to introduce a different node
for debug labels.

A semi-gross fix for a debug info issue. When inserting the "function start" label (i.e. first label in the entry block) take care to insert it at the beginning of the block.

Even though InsertAtEndOfBasicBlock is an ugly hack it still deserves a proper name. Rename it to EmitInstrWithCustomInserter since it does not necessarily insert
instruction at the end.

- Expand tabs... (poss 80-col violations, will get them later...)
- Consolidate logic for SelectDFormAddr and SelectDForm2Addr into a single
  function, simplifying maintenance. Also reduced custom instruction
  generation for SPUvecinsert/INSERT_MASK.
