a8e47b3319 store MC FP immediates as a double instead of as an APFloat, thus avoiding an 
unnecessary dtor for MCOperand.

d80781b98b 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.

26edbcb8d5 Add support for floating point immediates to MC instruction printing. ARM 
VFP instructions use it for loading some constants, so implement that
handling.

Not thrilled with adding a member to MCOperand, but not sure there's much of
a better option that's not pretty fragile (like putting a double in the
union instead and just assuming that's good enough). Suggestions welcome...

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

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.
