Puyan Lotfi 43e94b15ea Followup on Proposal to move MIR physical register namespace to '$' sigil.
Discussed here:

http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html

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.

Craig Topper 0d35edda90 [X86] In LowerTruncateVecI1, don't add SHL if the input is known to be all sign bits.
If the input is all sign bits then the LSB through MSB are all the same so we don't need to be move the LSB to the MSB.

Craig Topper f0f6eefb49 [X86] Add a DAG combine to widen (i4 (bitcast (v4i1))) before type legalization sees the i4 and changes to load/store.
Same for v2i1 and i2.

Craig Topper 742ac98d01 [X86] When lowering truncates to vXi1, don't sign extend i16/i8 types to 512-bit if we have VLX.
This should only affect what we do for v8i16. Previously we went to v8i64, but if we have VLX we only need v8i32. This prevents an unnecessary zmm usage.

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

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.

Zvi Rackover 7693733e80 [X86] Match bitcast of vxi1 to pmovmsk
Summary:
Add an early combine to match patterns such as:
  (i16 bitcast (v16i1 x))
  ->
  (i16 movmsk (v16i8 sext (v16i1 x)))

This combine needs to happen early enough before
type-legalization scalarizes the result of the setcc.

Dehao Chen 6b737ddce7 Add LiveRangeShrink pass to shrink live range within BB.
Summary: LiveRangeShrink pass moves instruction right after the definition with the same BB if the instruction and its operands all have more than one use. This pass is inexpensive and guarantees optimal live-range within BB.
