[WASM] Fix and fuse br_on_null/non_null in BBQ
https://bugs.webkit.org/show_bug.cgi?id=279701
rdar://135586113
Reviewed by Yusuke Suzuki.
Changes the BBQ implementations of br_on_null and br_on_non_null to
avoid calling addBranch() with an intermediate value. This resolves
some debug-only assertion failures with these instructions, and
also serves to fuse the compare and branch to make these instructions
a bit more efficient.
