  Log Message:
  -----------
  [MIRPrinter] Fix incorrect output of unnamed stack names

The MIRParser expects unnamed stack entries to have empty names ('').
In case of unnamed alloca instructions, the MIRPrinter would output
'<unnamed alloca>', which caused the MIRParser to reject the generated
code.
