2abf0134d0 I believe that the code generator now properly handles dead basic blocks. If not,
this is a bug, and should be fixed.

41c3157c70 In line with the previous patch, do not assert out if analyzing a dead basic block.

27c176234c Do not dereference end iterators. It hurts when you do that.

cd1a39bbec Fix a regression from r1.224. In particular, codegen a cast from double ->
float as a truncation by going through memory.  This truncation was being
skipped, which caused 175.vpr to fail after aggressive register promotion.

5a52b7aa36 Do not set the `link' bit when branching to the first BB of a function, as it
will cause an infinite loop.  The link bit is only used for calling functions.

7d6a9bf05c Initial checkin of a simple mod/ref analysis for global variables. This is
still overly conservative and uses very simple data structures, but it is a
start, and allows elimination of a lot of loads.

0cee4d2fb9 Trim whitespace.
Support cast of ints (and narrower) to float and double.
Support cast double to double (using load and store).
Abort if we see a CallInst or SetCondInst with long/fp args, instead
of producing bad code.
Support add, sub, mul, div of float and double.

78e3b3650e Now that the SparcV9 specific MachineCodeForInstruction class uses it's own
map on the side, Instruction no longer has to be Annotable.  This reduces
the size of the Instruction class by another 4 bytes (on a 32-bit system).

fd25f66f50 Do not find these ugly sparc-specific objects by using the annotation API on
instructions.  Instead, keep a map of instructions -> MCFI objects in the
already sparc-specific class MachineFunctionInfo.  This will slow down the
sparc backend a bit, but it does not penalize the rest of LLVM!

dd7c37af2e Eliminate the Instruction::iType field, folding it into the Value::VTy field.
This reduces the size of the instruction class by 4 bytes, and means that
isa<CallInst>(V) (for example) only needs to do one load from memory instead
of two.

f0870ad57b Get rid of Annotable's vtable. If anyone deletes an object through an Annotable*,
they get what they deserve.

This reduces the size of Instruction & Function by 4 bytes each.
