Log Message:
-----------
BBQJIT Splat 0/-1 should emit only one instruction
https://bugs.webkit.org/show_bug.cgi?id=257051
Reviewed by Yusuke Suzuki.
According to https://github.com/WebAssembly/design/issues/1476 at least one
person wants to encode vector 0 as Splat i32.const 0 since the former's
encoding is 18 bytes whereas the latter is 5 bytes. As such, we should emit
Splat i32.const 0/-1 as the optimal code in BBQJIT.
