Add WASM tail calls support to single-pass BBQ JIT
https://bugs.webkit.org/show_bug.cgi?id=253192
rdar://106448393
Reviewed by Justin Michaud and Yusuke Suzuki.
This is an old patch that I've had sitting around for a while but never got
around to
uploading. I put the tail call emit functions in their own function since they
are subtly different enough from the non-tail call versions it seemed more
complicated
to combine them. The main other interesting detail is that on x86_64 we don't
have enough
non-argument caller-save registers to hold the save FP/return PC. This means
they
get shuffled with the other parameters and then get popped later once the
shuffle is done.
