Chris Tate 0e67cd1e3b Place functions too large to inline by their own name ...

The helper keeps an internal function that exactly one other function
references in its referrer's partition, so the partition can inline it.
A program's module initializers are each called only from the entry
point, so all of them, with every single-use helper they call, shared
the entry point's partition. In the three.js nodes fixture that
partition held 1.1 million lines of LLVM IR, almost five times the
average, and set the native build's longest compile.

A function whose body is larger than 256 KiB of LLVM text is past
LLVM's inline cost limit even for the only call to a local function, so
it is now placed by the hash of its own name. Its own single-use
callees still stay with it.
