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.

Matthias Braun 79f85b3b8f MIRParser/MIRPrinter: Compute isSSA instead of printing/parsing it.
Specifying isSSA is an extra line at best and results in invalid MI at
worst. Compute the value instead.

Matthias Braun 538859cca3 llc: Add support for -run-pass none
This does not schedule any passes besides the ones necessary to
construct and print the machine function. This is useful to test .mir
file reading and printing.

Quentin Colombet 545e558b82 [MIR] Print on the given output instead of stderr.
Currently the MIR framework prints all its outputs (errors and actual
representation) on stderr.

This patch fixes that by printing the regular output in the output
specified with -o.

Justin Lebar c75d566f56 When printing MIR, output to errs() rather than outs().
Summary:
Without this, this command

  $ llvm-run llc -stop-after machine-cp -o - <( echo '' )

outputs an error, because we close stdout twice -- once when closing the
file opened for "-o", and again when closing outs().

Also clarify in the outs() definition that you can't ever call it if you
want to open your own raw_fd_ostream on stdout.

Alex Lorenz 0153e59935 Fix PR 24724 - The implicit register verifier shouldn't assume certain operand
order.

The implicit register verifier in the MIR parser should only check if the
instruction's default implicit operands are present in the instruction. It
should not check the order in which they occur.
