  Re-bootstrap PCT to remove broken-ness

Old bootstrap had bad code to generate contextuals, making it
impossible to rebootstrap without manual intervention.  That
intervention has now been done and code can move on.

  [pct]: Use tempreg in coerse, pirop, and Val

Have register coercion, :pasttype<pirop>, and PAST::Val use temporary
registers.  This greatly reduces the number of registers used in any
given sub.

  [pct]: No tempreg inside exception handlers

Temporary registers and exception handlers might not mix, so disable
temporary register generation while processing handlers.

PAST's built-in loop handlers ought to be safe, however.
