63b52693c8 The old getIndices has been deprecated, because it no longer works. It now 
is named getIndicesBROKEN() and shall be removed when the codebase is updated
to not call it

6e9422e14c When allocating space on stack for writing a register, 
use the size of the register, not the size of the Value type,
to get the right alignment.

value from size *before* subtracting size from offset!

c189997516 For phi elimination, now we are generating only one instruction 
using cpValue2Value instead of
passing vector to createCopyInstructionByType.

03fae5e5db Eliminate most uses of the machine instruction vector for each LLVM instr, 
since some m. instr. may be generated by LLVM instrs. in other blocks.
Handle non-SSA (anti and output) edges and true edges uniformly by
working with machine instructions alone.

6cd83556e6 Only add true dep. edges from an earlier to a later instruction. 
This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!
