Fix redundant decorations in IRParam (#4964)

* Fix redundant decorations in IRParam

Closes #4922

The problem was that same decorations were added to an IRParam multiple
times while running `specializeIRForEntryPoint()`.

`cloneGlobalValueWithCodeCommon()` kept cloning decorations for the
params that were already processed.
