Francis Visoiu Mistrih e76c5fcd70 [CodeGen] Print external symbols as $symbol in both MIR and debug output 
Work towards the unification of MIR and debug output by printing
`$symbol` instead of `<es:symbol>`.

Only debug syntax is affected.

Matthias Braun e2d2ce9ff1 PowerPC: Do not use llc -march in tests. 
`llc -march` is problematic because it only switches the target
architecture, but leaves the operating system unchanged. This
occasionally leads to indeterministic tests because the OS from
LLVM_DEFAULT_TARGET_TRIPLE is used.

However we can simply always use `llc -mtriple` instead. This changes
all the tests to do this to avoid people using -march when they copy and
paste parts of tests.

This patch:
- Removes -march if the .ll file already has a matching `target triple`
  directive or -mtriple argument.
- In all other cases changes -march=ppc32/-march=ppc64 to
  -mtriple=ppc32--/-mtriple=ppc64--

Jakob Stoklund Olesen 070fab8a1f Teach MachineInstr::isRegTiedToDefOperand() to correctly parse inline asm operands. 
The inline asm operands must be parsed from the first flag, you cannot assume
that an immediate operand preceeding a register use operand is the flag.
PowerPC "m" operands are represented as (flag, imm, reg) triples.
isRegTiedToDefOperand() would incorrectly interpret the imm as the flag.
