1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
named. Since it is just a predicate and isn't actually changing any state.
2) Added a missing return in the comments for setCurrentDwarfLoc() in
include/llvm/MC/MCContext.h for fix formatting.
3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
state.
4) Simplified the last test in isValidDwarfFileNumber() to just a one line
boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.

This is the last major patch to implement support for the .loc directive
...
and output the dwarf line number tables. This contains the code to emit and
encode the dwarf line tables from the previously gathered information in the
MCLineSection objects. This contains all the details to encode the line and
address deltas into the dwarf line table.
To do this an MCDwarfLineAddrFragment has been added.
Also this moves the interface code out of Mach-O streamer into
MCDwarf so it should be useable by other object file formats.
There is now one call to be made from an MCObjectStreamer
EmitInstruction() method:
MCLineEntry::Make(this, getCurrentSection());
to create a line entry after each instruction is assembled.
And one call call to be made from an MCObjectStreamer Finish() method:
MCDwarfFileTable::Emit(this, DwarfLineSection);
when getContext().hasDwarfFiles() is true and is passed a object file specific
MCSection where to emit the dwarf file and the line tables.
This appears to now be correct for 32-bit targets, at least x86. But the
relocation entries for 64-bit Darwin needs some further work which is next
up to work on. So for now the 64-bit Mach-O target does not output the
dwarf file and line tables.

Add a InitSections method to the streamer interface.
...
The ELF implementation now creates text, data and bss to match the gnu as
behavior.
The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.
A nice benefit is that -n is not required anymore when producing
ELF files.

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

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

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.
