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

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.

This is a patch to the assembler frontend to detect when aligning a text
...
section with TextAlignFillValue and calls EmitCodeAlignment() instead of
calling EmitValueToAlignment(). This allows x86 assembly code to be aligned
with optimal nops.

movw $8, (_cost_table_-L97$pb)+66(%eax)
After the parens, we could still have a binop.

Stop building RTTI information for *most* llvm libraries. Notable
...
missing ones are libsupport, libsystem and libvmcore. libvmcore is
currently blocked on bugpoint, which uses EH. Once it stops using
EH, we can switch it off.
This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.
