Right now DBG_LABEL are required for llvm.dbg.region_start and llvm.dbg.region_end in non-fast mode also.

Also, removed direct -ansi support from clang-cc.

   options, not be abused for individual tool argument translation.

 - Don't forward arbitrary -i* options to clang, just the ones we know
   about.

This introduces a small regression on the generated code
quality in the case we are just computing addresses, not
loading values.

Will work on it and on X86-64 support.

clang.
 - We will eventually want some more driver infrastructre for this
   probably.

 - For now, the clang-cc interface stays relatively the same, but we
   don't accept multiple instances anymore, or the [no-] variants
   directly.

When compiling in Thumb mode, only the low (R0-R7) registers are available
for most instructions. Breaking the low registers into a new register class
handles this. Uses of R12, SP, etc, are handled explicitly where needed
with copies inserted to move results into low registers where the rest of
the code generator can deal with them.

Types can have references to eachother, so we can't just call destroy on them.

Thanks to Duncan for noticing this

Tweak Sema::ActOnInstanceMessage() to look for a class method when dealing with qualified id's. This change is motivated by our desire to not support the "Class<foo>" idiom. Note that the change makes perfect sense (since all ObjC classes are also id/instances).

This allow us to document a simple migration path...change "Class <foo>" to "id <foo>".

This effects: 
- <rdar://problem/6761939> TASK: File source change radars for "qualified Class" errors
- <rdar://problem/6761864> Protocol qualified Class is unsupported
