Split CALL/FUNC recording.

Browse Source 
Record __call resolving and specialization for CALL* bytecodes.
Record argument adjustment and fast functions for FUNC* bytecodes.
Avoids all pending/immediate decisions for chained fast functions.
Cleaner semantics for pcall(), xpcall() and __tostring metamethod.
Prerequisite to drop the shadow frame link stack again.
