[JSC] Adjust delta for computeJumpType with thunk
https://bugs.webkit.org/show_bug.cgi?id=266326
rdar://119593801
Reviewed by Mark Lam.
When condition + jump gets compacted, it may affect on relative jump size for
thunk.
For non thunk cases, it does not affect since (1) backward jump will always
reduce
the gap and (2) forward jump is already using conservative value.
