Rafael Espindola 4f4363a490 Layout each section independently. With the testcase in PR8711: ...

before:
        4 assembler - Number of assembler layout and relaxation steps
    78563 assembler - Number of emitted assembler fragments
  8693904 assembler - Number of emitted object file bytes
   271223 assembler - Number of evaluated fixups
330771677 assembler - Number of fragment layouts
     5958 assembler - Number of relaxed instructions
  2508361 mcexpr    - Number of MCExpr evaluations

real	0m26.123s
user	0m25.694s
sys	0m0.388s

after:

      4 assembler - Number of assembler layout and relaxation steps
  78563 assembler - Number of emitted assembler fragments
8693904 assembler - Number of emitted object file bytes
 271223 assembler - Number of evaluated fixups
 231507 assembler - Number of fragment layouts
   5958 assembler - Number of relaxed instructions
2508361 mcexpr    - Number of MCExpr evaluations

real	0m2.500s
user	0m2.113s
sys	0m0.273s

And yes, the outputs are identical :-)

MCContext.h

It may not be an option to skip .debug_line if there are file reference in already emitted debug info. So, for now, emit dummy line table entry to make older linker and assemblers happy. This is not a new behavior, original AsmPrinter emitted similar line table entries.
