Justin Bogner 3135ba9b38 AsmPrinter: Use emitGlobalConstantFP to emit elements of constant data 
It's strange to duplicate the logic for emitting FP values into
emitGlobalConstantDataSequential, and it's even stranger that we end
up printing the verbose assembly comments differently between the two
paths. Just call into emitGlobalConstantFP rather than crudely
duplicating its logic.

James Y Knight 7c905063c5 Make utils/update_llc_test_checks.py note that the assertions are 
autogenerated.

Also update existing test cases which appear to be generated by it and
weren't modified (other than addition of the header) by rerunning it.
