it more tomorrow.

16f11212fc Teach LiveInterval::isZeroLength about null SlotIndexes. 
When instructions are deleted, they leave tombstone SlotIndex entries.
The isZeroLength method should ignore these null indexes.

This causes RABasic to sometimes spill a callee-saved register in the
abi-isel.ll test, so don't run that test with -regalloc=basic.  Prioritizing
register allocation according to spill weight can cause more registers to be
used.

7181ae008c ExecutionEngine: push TargetMachine creation into clients (v2) 
In particular, into EngineBuilder. This should only impact
the private API between the EE and EB classes, not external
clients, since JITCtor and MCJITCtor are both protected members.

ed5d966802 Teach the RtDyld to tell the memory manager about how much space a function 
actually takes rather than how much memory was allocated for it. This
is more accurate and should help the manager pack things more effectively.

59864a5443 Re-add the autoconf rule for the docs/doxygen.cfg file.

At the same time, add an optional rule for clang's doxygen.cfg.
