src/bigint.c: implement multi-precision integer.

To enable multi-precision integer support, you need to link
`mruby-bigint` mrbgem. The gem itself is empty but it turns on
the "bigint" support.

Functions listed in `mruby/internal.h` can be called from:

* gems (mrbgems/**/*.c)
But not from the application linked with `libmruby`.

Get object properties after mrb_get_args()
...
ref. #5613
I checked with Valgrind, and the methods that can cause use-after-free are `Array#rotate`, `Array#rotate!`, and `String#byteslice`.
Since `String#rindex` uses `RSTRING_LEN()` indirectly inside the function, no reference to the out-of-bounds range is generated.

mruby/ops.h: add new instructions OP_GETIDX and OP_SETIDX.
...
Which represent `obj[int]` and `obj[int]=val` respectively where `obj`
is either `string`, `array` or `hash`, so that index access could be
faster. When `obj` is not assumed type or `R(a+1)` is not integer, the
instructions fallback to method calls.
