Bill Wendling 1214860a78 Use StringMap for greater justice!

Bill Wendling 4bb9089db7 Don't return std::vector by value, but pass it in by reference to be filled.

Bill Wendling 2e50689435 Revert my previous check-in that split up MachineModuleInfo. It turns out to 
slow the compiler down at -O0 some 30% or more. Ooops.

Bill Wendling 536fb95321 Use the canonical form for getting an empty structure.

Bill Wendling 82a9321f56 Sorry. I couldn't sleep at night knowing I put these ugly casts into the source tree.

Bill Wendling c8cdb883df - Update comments. 
- Don't use GlobalVariable::LinkageTypes when unsigned works.

Evan Cheng da3db11db3 - Re-apply 52748 and friends with fix. GetConstantStringInfo() returns an empty string for ConstantAggregateZero case which surprises selectiondag. 
- Correctly handle memcpy from constant string which is zero-initialized.

Anton Korobeynikov a7c583d584 Revert (52748 and friends): 
Move GetConstantStringInfo to lib/Analysis. Remove
string output routine from Constant. Update all
callers. Change debug intrinsic api slightly to
accomodate move of routine, these now return values
instead of strings.

This unbreaks llvm-gcc bootstrap.

Bill Wendling 196c78f0be Reduce number of times .size() is called on a vector. Rename some variables to 
match normal naming scheme.

Bill Wendling f96d046d7c - Remove a use of std::vector. 
- Make sure that we're not recalculating the size of a vector
  that never changes.

Bill Wendling c758698d2c 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!

Dan Gohman d78c400b5b 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.

Dale Johannesen fd967cf3fa 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.

Dan Gohman bdc24adaaf 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.

Evan Cheng efd142a920 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.

Evan Cheng 263070ea2b Rename RecordLabel to RecordSourceLine because that's what it is doing.

Evan Cheng 1c6c16ea11 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.

Dale Johannesen 56d4903db5 Accept getelementptr starting at GV with all 0 indices as a 
legitimate way of representing global variable GV in debug info.
