Softlink jruby to jruby.bash instead of hard copy.
[IR] Strip no-longer-needed ensure-map and related state

* git 27442fc0 fixed some bugs in the interpreter that effectively
  used the rescue map for handling both rescue and ensures which
  left the ensure map unused.

* This patch got rid of the ensure map and all related state from
  the IR builder, instructions, CFG, and exception regions.

* Verified that there is no change in spec test results especially
  since the CFG removed exception edges to ensure-block, which could
  potentially have affected accuracy of the opt. passes.
Fixed bad branch merge from f3293274
[IR] Added missing flags on TO_ARY operation -- fixes buggy opts.

* TO_ARY operation can raise an exception (TypeError) and can have
  side effects (allocates RubyArray). So, optimizations like DCE
  cannot delete this instruction. Adding the flags blocks DCE from
  doing so and fixes mspec failures when run with DCE enabled.
[IR] Fixed off-by-1 error replacing instruction in an instr array

* Fixes occasional crasher running mspec with
  AddLocalVarLoadStoreInstructions pass enabled.
