-----------
[WGSL] Only rewrite globals in callees once
https://bugs.webkit.org/show_bug.cgi?id=257716
rdar://110265430
Reviewed by Dan Glastonbury.
A callee might be reached through multiple paths in the call graph (e.g. f->h
and
f->g->h), so we need to keep track of the callees we already visited. However,
when
we encounter a callee we already visited we (might) still need to rewrite all
the
call sites to that callee if its signature was modified (i.e. if it needs global
variable(s) to be passed to it).
