In-place interpreter: fix clobbered register in call and reduce memory usage
for if and br
https://bugs.webkit.org/show_bug.cgi?id=260471
rdar://114218539
Reviewed by Yusuke Suzuki.
Updated `call` instruction to save caller save registers around the operation
call.
Reduce memory usage for if and br by 3B by saving the size of the instruction
instead of the next PC.
