257d2dafbd Testcase for 94996 (PR 6157)

d5575f29f1 Generate DEBUG_VALUE comments on x86. The (limited) 
dbg.declare's we currently generate go through both
register allocators without perturbing the results.

7771b7c621 If a instruction belongs to another function (and not current function) as per debug info attached with the instruction then ignore the dangling lexical scope of this instruction. Such scopes are unreachable.

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.

be94f23992 Remove dead debug info intrinsics. 
Intrinsic::dbg_stoppoint
 Intrinsic::dbg_region_start 
 Intrinsic::dbg_region_end 
 Intrinsic::dbg_func_start

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.

02aac922b4 Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well. 
This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

64e6529e76 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.
