	Make io_fwrite safe for compaction

	[Bug #20169]

	Embedded strings are not safe for system calls without the GVL because
	compaction can cause pages to be locked causing the operation to fail
	with EFAULT. This commit changes io_fwrite to use rb_str_tmp_frozen_no_embed_acquire,
	which guarantees that the return string is not embedded.

Use shared flags of the type

2022-11-02T15:03:21+00:00

The ELTS_SHARED flag is generic, so we should prefer to use the flags
specific of the type (STR_SHARED for strings and RARRAY_SHARED_FLAG
for arrays).

Add comments about special runtime routines YJIT calls

2021-10-20T22:19:43+00:00

When YJIT make calls to routines without reconstructing interpreter
state through jit_prepare_routine_call(), it relies on the routine to
never allocate, raise, and push/pop control frames. Comment about this
on the routines that YJTI calls.

This is probably something we should dynamically verify on debug builds.
It's hard to statically verify this as it requires verifying all
functions in the call tree. Maybe something to look at in the future.
