Log Message:
-----------
Streaming compiler does not reject mixed legacy and spec-correct EH
https://bugs.webkit.org/show_bug.cgi?id=315365
rdar://177030377
Reviewed by Yijia Huang.
Legacy EH instructions are not defined in the wasm spec but are still
supported for backwards compatibility. Functions must either use legacy
or standards compliant EH instructions but not both, and the streaming
compiler needs to be updated to enforce this.
