In preparation for adding support for named vregs we are changing the sigil for
physical registers in MIR to '$' from '%'. This will prevent name clashes of
named physical register with named vregs.

As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.
The MIR printer prints the IR name of a MBB only for block definitions.

As part of the unification of the debug format and the MIR format,
always print registers as lowercase.
* Only debug printing is affected. It now follows MIR.

The dream of a unified check-line auto-generator for all phases of compilation is dead.
The llc script has already diverged to be better at its goal, so having 2 scripts that
do almost the same thing is just causing confusion for newcomers. I plan to fix up more
x86 tests in a next commit. We can rip out the llc ability in update_test_checks.py after
that.

This bug was exposed by using nsw/nuw for more aggressive folds in:

The changes mimic the IR demanded bits logic in InstCombiner::SimplifyDemandedUseBits(),
but we can't just flip flag bits in the DAG; we have to create a new node that has the
bits cleared.
This should fix:
