f713384be5 Factoring and potential bug fix. The elf "flags" cannot be used as masks.
For example, setting STT_OBJECT (1) and STT_FUNC (2), should not produce
a STT_SECTION (3).

cbf8a98c7c fix the asmparser so that the target is responsible for skipping to
the end of the line on a parser error, allowing skipping to happen
for syntactic errors but not for semantic errors.  Before we would
miss emitting a diagnostic about the second line, because we skipped
it due to the semantic error on the first line:

  foo %eax
  bar %al

This fixes rdar://8414033 - llvm-mc ignores lines after an invalid instruction mnemonic errors

1ab6f2fa7a llvm-mc: Don't crash when using -n and we see a directive before the initial section.
- This is annoying, because we have to scatter this check everywhere that could emit real data, but I see no better solution.

232ab949d5 This is the second of three patches to implement support for the .loc directive
and output the dwarf line number tables.  This takes the current loc info after
an instruction is assembled and saves the needed info into an object that has
vector and for each section.  These objects will be used for the final patch to 
build and emit the encoded dwarf line number tables.  Again for now this is only
in the Mach-O streamer but at some point will move to a more generic place.

c1840b3da2 First bit of support for the dwarf .loc directive. This patch updates the
needed parsing for the .loc directive and saves the current info from that
into the context.  The next patch will take the current loc info after an
instruction is assembled and save that info into a vector for each section for
use to build the line number tables.  The patch after that will encode the info
from those vectors into the output file as the dwarf line tables.
