71a27d5aa6 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.

79c9e03097 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

a55e563b84 XFAIL this test for powerpc. 
This test relies on iSel lowering dbg_declare intrinsic when CodeGen::OptLevel is None. On PPC side, CodeGen::OptLevel stays to default when -O0 is used on the command line.

4853c9c8d1 Remove test to check bugfix in handing debug info for global variables using intrinsics. Now, debug info for global variable is encoded using metadata. The old code path is now history and there is no need to have a test to check a bug fix in old code path.

0b8b2713d3 Enable code to emit dbg.declare as DEBUG_VALUE 
comments (fast isel, X86).  This doesn't seem
to break any functionality, but will introduce
cases where -g affects the generated code.  I'll
be fixing that.

c1b5223e76 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.

d5a8051dea Remove tests that are not suitable anymore. Plus they are not testing the original bugfixes anymore. These tests were inserted to check bug fixes in code that handled debug info intrinsics. These intrinsics are no longer used and now llvm parser simply ignores old .dbg intrinsics from these dead tests.
