change also hadn't fixed the most obvious problem -- assuming that i64 will
only be bitconverted to f64, ignoring the various vector types.

to determine where to place PHIs by iteratively comparing reaching definitions
at each block.  That was just plain wrong.  This version now computes the
dominator tree within the subset of the CFG where PHIs may need to be placed,
and then places the PHIs in the iterated dominance frontier of each definition.
The rest of the patch is mostly the same, with a few more performance
improvements added in.

Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

to keep the node entries in scc_iterator up to date instead of dangling as
the SCC mutates.

This is a really terrible problem which was causing -g to affect codegen 
because it would permute the memory image of the compiler process.
