[JSC] Atomic instructions in IPInt should not have metadata if it does not
call functions
https://bugs.webkit.org/show_bug.cgi?id=312227
rdar://174706330
Reviewed by Keith Miller.
This patch drops most of metadata for atomic instructions by using the
same mechanism in normal load/store and SIMD load/store. We add a fast
path and a slow path which handles complicated LEB decoding completely.
Also now pointer construction code is completely unified by using the
helper macros defined for fast and slow path of these memory related
operations.
