k0kubun 6dd4657fc2 _mjit_compile_send.erb: retry inlining attr_reader
This reverts r63249 (revert r63212) and fixes a bug in it. The test to
prevent the bug is added as well.

vm_insnhelper.c: add `index` argument to vm_getivar. The argument is
created so that MJIT can pass the value of `cc->aux.index` on compilation
time.  The cache invalidation in _mjit_compile_send_guard.erb is only
working for the cache value on compilation time.
Note: As `index` is always passed as constant and it's force-inlined,
the performance of `vm_getivar` won't be degraded in VM.

_mjit_compile_send_guard.erb: New. Used to invalidate inlined values of cc.
common.mk: update dependencies for _mjit_compile_send_guard.erb
