_mjit_compile_pc_and_sp.erb: skip moving pc
when catch_except_p is false and insn.always_leaf? is true (never makes
arbitrary method call in the insn).
On Optcarrot, unfortunately this didn't have measureable performance impact.
But still this is a good direction since it becomes much faster when
marking all insns as always leaf.
bare_instructions.rb: add `#always_leaf?` that indicates the insn can
always be considered as leaf. Using dynamic leaf for JIT would be hard
since it requires to discard outdated code somehow.
