Allow controlling which address is used for instructions created when inlining during analysis

Previously the address of the instruction in the function being inlined
was used as the new instruction's address when copying it during
inlining. Now there is an additional option: use the address of the
call instruction that is being replaced as the new instruction's
address.

This new mode is useful when inlining thunks or stub functions, but care
must be taken if using it beyond that.

The benefit is that it ensures that when a function contains multiple
calls to the same stub function, each inlined copy ends up with distinct
addresses. This ensures that call type adjustments and other overrides
that are stored on the function and keyed by address can be applied
independently to each callsite that was inlined.

The trade-off is that if the function being inlined contains non-trivial
logic, all of the inlined instructions sharing an address will limit
what type of adjustments can be applied to them.

The Objective-C and shared cache workflows are updated to take advantage
of this new mode when they enable inlining of stub functions. This will
make it possible for multiple calls to the same runtime function within
a single function to have separate call type adjustments applied in the
future.
