Log Message:
-----------
[JSC] Update the description of CallFrame::argumentCountIncludingThis for
Wasm callees
https://bugs.webkit.org/show_bug.cgi?id=312388
rdar://174847751
Reviewed by Keith Miller.
The comment describing CallFrame layout says that the value
argumentCountIncludingThis
slot is not meaningful in Wasm code. That is incorrect. Update the comment to
describe
how it stores the call site index in the upper 32 bits. Also add a note about
the
use of the arg0 slot for multi-value return in Wasm.
Doc-only change, no new tests.
