Francis Visoiu Mistrih a8a83d150f [CodeGen] Use MachineOperand::print in the MIRPrinter for MO_Register. 
Work towards the unification of MIR and debug output by refactoring the
interfaces.

For MachineOperand::print, keep a simple version that can be easily called
from `dump()`, and a more complex one which will be called from both the
MIRPrinter and MachineInstr::print.

Add extra checks inside MachineOperand for detached operands (operands
with getParent() == nullptr).

Francis Visoiu Mistrih 25528d6de7 [CodeGen] Unify MBB reference format in both MIR and debug output 
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.

Francis Visoiu Mistrih 9d7bb0cb40 [CodeGen] Print register names in lowercase in both MIR and debug output 
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.

Sanjay Patel f31b1a00ea [DAGCombiner] fold assertzexts separated by trunc 
If we have an AssertZext of a truncated value that has already been AssertZext'ed, 
we can assert on the wider source op to improve the zext-y knowledge:
 assert (trunc (assert X, i8) to iN), i1 --> trunc (assert X, i1) to iN

This moves a fold from being Mips-specific to general combining, and x86 shows
improvements.

Sanjay Patel 5e7b7b7503 [x86] regenerate checks with update_llc_test_checks.py 
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.

We can rip out the llc ability in update_test_checks.py next and rename it, so it will
be clear that we have one script for llc check auto-generation and another for opt.

Sanjay Patel 3a3aaf67e0 [DAG] optimize negation of bool 
Use mask and negate for legalization of i1 source type with SIGN_EXTEND_INREG.
With the mask, this should be no worse than 2 shifts. The mask can be eliminated
in some cases, so that should be better than 2 shifts.

This change exposed some missing folds related to negation:

There may be others, so please let me know if you see any regressions.
