This fix just makes sure to construct the global with the appropriate 
type, and fixes up the one user this affects to compensate.

be any regressions from this on my machine, but please let me know if 
you run into issues.  (The idea here is that it's better to run all

Speculatively execute a block when the the block is the then part of a triangle shape and it contains a single, side effect free, cheap instruction. The branch is eliminated by adding a select instruction. i.e.

will update the CFG if it decides to create an unconditional rather than a conditional branch.

horrible hack, and must be removed eventually.

clear what to do (FIXMEs included in the patch).
