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'.

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.

Don't coalesce identical DBG_VALUE instructions prematurely.

Each of these instructions may have a RegsClobberInsn entry that can't be

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.

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.

Instead encode llvm IR level property "HasSideEffects" in an operand (shared
