  [JSC][armv7] InlineCacheCompiler::emitProxyObjectAccess: restore metadataTableRegister before call
https://bugs.webkit.org/show_bug.cgi?id=277683

Reviewed by Justin Michaud.

While metadataTableRegister is saved/restored by the IC, it emits
a JS call inbetween doing so. This rematerialzes metadataTableRegister before
the call so that the callee sees the correct value.
