R600/SI: Custom lower SI_IF and SI_ELSE to avoid machine verifier errors

SI_IF and SI_ELSE are terminators which also produce a value.  For
these instructions ISel always inserts a COPY to move their value
to another basic block.  This COPY ends up between SI_(IF|ELSE)
and the S_BRANCH* instruction at the end of the block.

This breaks MachineBasicBlock::getFirstTerminator() and also the
machine verifier which assumes that terminators are grouped together at
the end of blocks.

To solve this we coalesce the copy away right after ISel to make sure
there are no instructions in between terminators at the end of blocks.

Remove DwarfUnit::LabelRange since it's unused.

Seems at some point the intent was to emit fission ranges_base as unique
per CU but the code today emits ranges_base as the start of the ranges
section for all CUs being compiled and all the ranges_base relative
addresses are relative to that. So removing this dead code and leaving
the status quo until there's a reason to change it (perhaps something's
faster if it has distinct ranges for each CU).
