735419dfe7 DwarfWrite is now smart enough to drop debug value pointing to undefined register. Update this test to avoid this. 
iSel not properly lowring argument into a well formed DBG_VALUE in some cases is a separate issue and not related to the test in this testcase.

57bd643113 Let's try one more time to match patterns. 
The goal is to match following 3 lines. In otherwords, a temp. label between to DEBUG_VALUE comments.
        ;DEBUG_VALUE: bar:x <- undef   ## 2010-01-18-Inlined-Debug.c:7
Ltmp1:
        ;DEBUG_VALUE: foo:__x <- undef ## 2010-01-18-Inlined-Debug.c:5

3a32865d58 Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast).

It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.

26c6cf4cec It's possible for a global variable to be optimized out of a metadata object. So 
we should allow a "null" with this dyn_cast.

9450b0e1a6 Move the dominator verification code out of special code embedded within 
the PassManager code into a regular verifyAnalysis method.

Also, reorganize loop verification. Make the LoopPass infrastructure
call verifyLoop as needed instead of having LoopInfo::verifyAnalysis
check every loop in the function after each looop pass. Add a new
command-line argument, -verify-loop-info, to enable the expensive
full checking.

daf9e02893 llvm.dbg.region.end() intrinsic is not required to be in _last_ basic block in a function. If that happens then any basic block that follows (lexically) the block with regin.end will not have scope info available. LexicalScopeStack relies on processing basic block in CFG order, but this processing order is not guaranteed. Things get complicated when the optimizer gets a chance to optimizer IR with dbg intrinsics. 
Apply defensive patch to preserve at least one lexical scope till the end of function.

be8cc2a3de Second attempt: 
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

5aa4977fba - 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.
