Add new build option KERNEL_USE, which compiles with -mkernel and gets propogated to CFLAGS. Use this to call panic() instead of abort() when enabled.

 - Fiddling with abort directly is annoying given the way we use system includes, although it would be nice to fix this so we could make sure calling abort directly is verboten.

were paying.

instructions.  In addition to being a convenience,
they are faster than the old apis, particularly when
not going from an MDKindID like people should be
doing.

IRGen: Move the auxiliary data structures tracking AST -> LLVM mappings out of CodeGenTypes, to per-record CGRecordLayout structures.
 - I did a cursory check that this was perf neutral, FWIW.

CGRecordLayoutBuilder: Switch unions to use same mechanism for tracking field and bit-field info as structs.
 - Anders, please check.

the storage of !dbg metadata kinds in the instruction themselves.
The on-the-side hash table works great for metadata that not-all
instructions get, or for metadata that only exists when optimizing.
But when compile-time is everything, it isn't great.

I'm not super thrilled with the fact that this plops a TrackingVH in
Instruction, because it grows it by 3 words.  I'm investigating 
alternatives, but this should be a step in the right direction in any
case.
