[dev.regabi] cmd/compile: rename ir.Find to ir.Any and update uses

Browse source 
ir.Find is called "any" in C#, Dart, Haskell, Python, R, Ruby, and Rust,
and "any_of" in C++, "anyMatch" in Java, "some" in JavaScript,
"exists in OCaml, and "existsb" in Coq.
(Thanks to Matthew Dempsky for the research.)

This CL changes Find to Any to use the mostly standard name.

It also updates wrapper helpers to use the any terminology:
	hasCall -> anyCall
	hasCallOrChan -> anyCallOrChan
	hasSideEffects -> anySideEffects

Unchanged are "hasNamedResults", "hasUniquePos", and "hasDefaultCase",
which are all about a single node, not any node in the IR tree.

I also renamed hasFall to endsInFallthrough, since its semantics are
neither that of "any" nor that of the remaining "has" functions.

So the new terminology helps separate different kinds of predicates nicely.
