Devang Patel 03f0a2fba0 DebugLabelFolder ruthlessly deletes redundant labels. However, sometimes the redundant labels is referenced by debug info somewhere else. This patch provies a way so that dwarf writer can mark labels as used.

Devang Patel bbdc8207d5 Removoe MachineModuleInfo methods (and related DebugInfoDesc class hierarchy) that were used to handle debug info.

Evan Cheng 94ea5be39f Fix a couple of Dwarf bugs. 
- Emit DW_AT_byte_size for struct and union of size zero.
- Emit DW_AT_declaration for forward type declaration.

Chris Lattner 4d557e4872 Fix an over aggressive assumption that struct decls will have a pointer to 
an array that is empty.  Instead of requiring this array, allow a null pointer.
This shrinks all forward references of structs.

Dan Gohman 7ddcadc7ee Move the include of MachineLocation.h into MachineModuleInfo.h 
because it declares a std::vector<MachineMove>, and strict
concept checking requires the definition of MachineMove to be
available.

Bill Wendling 3e30cbb457 Make the DICountVisitor not a visitor. This keeps us from calling virtual 
functions and junk.

Bill Wendling 10fff6078a 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 a28cd12b06 - Update comments. 
- Don't use GlobalVariable::LinkageTypes when unsigned works.

Evan Cheng 0ff39b3feb - 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 6d116bc7ce 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 e6b6bae536 - Remove a use of std::vector. 
- Make sure that we're not recalculating the size of a vector
  that never changes.
