[MemoryBuiltins] Don't query TLI for non-pointer functions (NFC)

Fetching allocation data for calls is a rather hot operation, and
TLI lookups are slow. We can greatly reduce the number of calls
for which TLI is queried by checking that they return a pointer
value first, as this is a requirement for allocation functions
anyway.
