019922d1b0 Do not emit specification DIE with DW_AT_specification attribute for member functions of a funcation local class. This trips gdb's partial scan of DIEs at load time. Fixes Radar 7833483.

d8425df136 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.

0c90d43b70 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.

b324e66f4c 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.

e52b1fa128 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.

3dc625cdce 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.

4dbb301f17 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.
