f20c4f715f This mechanical patch moves type handling into CompileUnit from DwarfDebug. In case of multiple compile unit in one object file, each compile unit is responsible for its own set of type entries anyway. This refactoring makes this obvious.

e39647951b Do not emit DW_AT_upper_bound and DW_AT_lower_bound for unbouded array. 
If lower bound is more then upper bound then consider it is an unbounded array.
An array is unbounded if non-zero lower bound is same as upper bound.
If lower bound and upper bound are zero than array has one element.

9a624fa993 Collect and coalesce DBG_VALUE instructions before emitting the function. 
Correctly terminate the range of register DBG_VALUEs when the register is
clobbered or when the basic block ends.

The code is now ready to deal with variables that are sometimes in a register
and sometimes on the stack. We just need to teach emitDebugLoc to say 'stack
slot'.

1886a4c823 Emit less labels for debug info and stop emitting .loc directives for DBG_VALUEs. 
The .dot directives don't need labels, that is a leftover from when we created
line number info manually.

Instructions following a DBG_VALUE can share its label since the DBG_VALUE
doesn't produce any code.

e01b75cb89 Keep track of directory namd and fIx regression caused by Rafael's patch r119613.

a87d80cdca Don't coalesce identical DBG_VALUE instructions prematurely. 
Each of these instructions may have a RegsClobberInsn entry that can't be
ignored. Consecutive ranges are coalesced later when DwarfDebug::emitDebugLoc
merges entries.

ec0ac3ca40 Reapply r128045 and r128051 with fixes. 
This will extend the ranges of debug info variables in registers until they are
clobbered.

Fix 1: Don't mistake DBG_VALUE instructions referring to incoming arguments on
the stack with DBG_VALUE instructions referring to variables in the frame
pointer. This fixes the gdb test-suite failure.

Fix 2: Don't trace through copies to physical registers setting up call
arguments. These registers are call clobbered, and the source register is more
likely to be a callee-saved register that can be extended through the call
instruction.

9c057ee440 Dont emit 'DBG_VALUE %noreg, ...' to terminate user variable ranges. 
These ranges get completely jumbled by the post-ra scheduler, and it is not
really reasonable to expect it to make sense of them.

Instead, teach DwarfDebug to notice when user variables in registers are
clobbered, and terminate the ranges there.

d12c0a2764 Ignore DBG_VALUE machine instructions while constructing instruction ranges based on location info. 
Machine instruction range consisting of only DBG_VALUE MIs only contributes consecutive labels in assembly output, which is harmless, and empty scope entry in DebugInfo, which confuses debugger tools.
