Debug Info: LiveDebugVarible can remove DBG_VALUEs, make sure we emit them back. RegisterCoalescer used to depend on LiveDebugVariable. LDV removes DBG_VALUEs without emitting them at the end. We fix this by removing LDV from RegisterCoalescer. Also add an assertion to make sure we call emitDebugValues if DBG_VALUEs are removed at runOnMachineFunction. rdar://problem/13183203 Reviewed by Andy & Jakob llvm-svn: 175023

DebugInfo: Following up to r209677, refactor local variable emission to delay the choice between emitting the definition attributes or using DW_AT_abstract_definition This doesn't fix the abstract variable handling yet, but it introduces a similar delay mechanism as was added for subprograms, causing DW_AT_location to be reordered to the beginning of the attribute list for local variables, and fixes all the test fallout for that. A subsequent commit will remove the abstract variable handling in DbgVariable and just do the abstract variable lookup at module end to ensure that abstract variables introduced after their concrete counterparts are appropriately referenced by the concrete variable. llvm-svn: 210943

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.

Debug Info: LiveDebugVarible can remove DBG_VALUEs, make sure we emit them back. RegisterCoalescer used to depend on LiveDebugVariable. LDV removes DBG_VALUEs without emitting them at the end. We fix this by removing LDV from RegisterCoalescer. Also add an assertion to make sure we call emitDebugValues if DBG_VALUEs are removed at runOnMachineFunction. rdar://problem/13183203 Reviewed by Andy & Jakob llvm-svn: 175023
