Use the canonical way to get an empty structure.

Use StringMap for greater justice!

Don't return std::vector by value, but pass it in by reference to be filled.

Revert my previous check-in that split up MachineModuleInfo. It turns out to
slow the compiler down at -O0 some 30% or more. Ooops.

Sorry. I couldn't sleep at night knowing I put these ugly casts into the source tree.

This unbreaks llvm-gcc bootstrap.

Reduce number of times .size() is called on a vector. Rename some variables to
match normal naming scheme.

Reverting broken patch r52803.

- Remove a use of std::vector.
- Make sure that we're not recalculating the size of a vector
that never changes.

Refactor the DebugInfoDesc stuff out of the MachineModuleInfo file. Clean up
some uses of std::vector, where it's return std::vector by value. Yuck!

Don't create a whole new string just to copy the elements into it.

Clean up the use of static and anonymous namespaces. This turned up
several things that were neither in an anonymous namespace nor static
but not intended to be global.

Recommitting EH patch; this should answer most of the
review feedback.
-enable-eh is still accepted but doesn't do anything.
EH intrinsics use Dwarf EH if the target supports that,
and are handled by LowerInvoke otherwise.
The separation of the EH table and frame move data is,
I think, logically figured out, but either one still
causes full EH info to be generated (not sure how to
split the metadata correctly).
MachineModuleInfo::needsFrameInfo is no longer used and
is removed.

A quick nm audit turned up several fixed tables and objects that were
marked read-write. Use const so that they can be allocated in a
read-only segment.

SDIsel processes llvm.dbg.declare by recording the variable debug information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc.
Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes.
For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time.

Rename RecordLabel to RecordSourceLine because that's what it is doing.

Add an extra operand to LABEL nodes which distinguishes between debug, EH, or misc labels. This fixes the EH breakage. However I am not convinced this is *the* solution.
