Eric Christopher a258c62ea1 If we're emitting additional CIEs due to personality functions 
don't emit the default one. Explicitly check for the NULL
CIE later.

Chris Lattner 58f9bb2ccd implement a new magic global "llvm.compiler.used" which is like llvm.used, but 
doesn't cause ".no_dead_strip" to be emitted on darwin.

Torok Edwin fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

Devang Patel 61b35cd15e 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 3c82aa0209 Removoe MachineModuleInfo methods (and related DebugInfoDesc class hierarchy) that were used to handle debug info.

Devang Patel 7b13aeedea Keep "has debug info" big in MachineModuleInfo to avoid circular dependency between AsmPrinter and CodeGen.

Evan Cheng 288fbd2133 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 bc09b36016 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 6613991eae 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.

Evan Cheng 962c2cf17a Instead of setPreservesAll, just mark them preseving machine loop info and machine dominators.

Bill Wendling 88d2506ae2 Make the DICountVisitor not a visitor. This keeps us from calling virtual 
functions and junk.

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.
