The invocation count is part of call feedback, and is used during
tier-up to determine inlining candidates. For bytecode, it is updated
by the InterpreterEntryTrampoline, which can be seen as a global
prologue for all bytecode functions.

Since NCI tiers up, it must also track the invocation count. This CL
adds it to the NCI prologue sequence (emitted as part of every NCI
code object).
