a83bba46b3 Reverting r135232. It's causing infinite looping in DbgScope::openInsnRange.

597a7664e1 Producing a DW_FORM_addr for DW_AT_stmt_list is probably correct, but 
it is both inefficient and unexpected by dwarfdump. Change to
a DW_FORM_data4.

While in here, change the predicate name to reflect that the position
is not really absolute (it is an offset), just that the linker needs a
relocation.

adb877d62e 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'.

15a3ea0628 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.

28cf1156c9 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.

e17232ee4d 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.

c3f5f783a2 First cut at supporting .debug_loc section. 
This is used to track variable information.

295cdf8b82 Do not emit line number entries for unknown debug values. 
This fixes recent regression in store.exp from gdb testsuite.

163a9f7c5f Enable multiple Compile Units in one module. 
This means now 'llvm-ld a.bc b.bc' will preserve debug info appropriately.

increase in the debug line info section, and it's causing
regressions in a gdb testsuite.
