[PATCH] D71629: [SystemZ] Recognize mrecord-mcount in backend

[Jonas Paulsson via Phabricator via llvm-commits]

Patch updated to call EmitLabel, SwitchSection() and EmitIntValue() instead of emitting raw text.

I don't know why gcc is emitting a "1:" label... Is it OK to instead emit .Ltmp0:, .Ltmp1: labels (any name) for each fentry?

Not exactly sure exactly what type of section should be created, but calling getELFSection() this way gives the right output, it seems.

Switching back to the previous section causes a ".text" to be printed instead of ".previous".

See mrecord-mcount-01.ll for the output...
