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

1b346b7f8f Enable code to emit dbg.declare as DEBUG_VALUE

be fixing that.

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). 
This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.
It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.
