Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.

There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

TargetLoweringObjectFileImpl down to MCObjectFileInfo.

TargetAsmInfo is done to one last method. It's *almost* gone!

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.

Make the StringMaps attached to MCContext use the MCContext's allocator;
reduces the number of calls to malloc().

Don't store Twine temporaries, it's not safe.

MC: Add support for disabling "temporary label" behavior. Useful for debugging
on Darwin.

Remove duplicated code.

Fixed version of 121434 with no new memory leaks.

Revert my previous patch to make the valgrind bots happy.

Initial support for the cfi directives. This is just enough to get

.cfi_startproc
nop
.cfi_endproc

Rename temporary symbols if they conflict with artificial symbols created
by the assembler. This was blocking parsing any large .s produced by clang for
example.

Fixes PR8596.

Fix Whitespace.

Add .loc methods to the streamer.

Next: Add support for the !HasDotLocAndDotFile case to the MCAsmStreamer
and then switch codegen to use it.

Parse and remember discriminators in .loc line. I try to output them with
another patch.
This lets us parse a bit more of the gcc 4.5 output.

Fixed version of 118639 with an extra assert to catch similar problems

Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel!

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.

Move logic of determining ELF entsize from the .s printer to initialization
time. That way, the EntrySize field is initialized for other code paths,
namely, the .ll -> .o code path.

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.

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.
