  [MLIR][Support] A cache for cyclical replacers/maps (#98202)

This is a support data structure that acts as a cache for replacer-like
functions that map values between two domains. The difference compared
to just using a map to cache in-out pairs is that this class is able to
handle replacer logic that is self-recursive (and thus may cause
infinite recursion in the naive case).

This class provides a hook for the user to perform cycle pruning when a
cycle is identified, and is able to perform context-sensitive caching so
that the replacement result for an input that is part of a pruned cycle
can be distinct from the replacement result for the same input when it
is not part of a cycle.

In addition, this class allows deferring cycle pruning until specific
inputs are repeated. This is useful for cases where not all elements in
a cycle can perform pruning. The user still must guarantee that at least
one element in any given cycle can perform pruning. Even if not, an
assertion will eventually be tripped instead of infinite recursion (the
run-time is linearly bounded by the maximum cycle length of its input).

  [MCParser] .altmacro: Support argument expansion not preceded by \

In the .altmacro mode, an argument can be expanded even if not preceded
by \. This behavior is not enabled for Darwin, which uses $
(`isIdentifierChar('$')` is true) for macro expansion.

This is f8b1ca4992a22b4b65282c09dd6f07a1a2839070 with a fix.

  [ArgPromotion] Handle pointer arguments of recursive calls (#78735)

Argument promotion doesn't handle recursive function calls to promote
arguments. This patch adds functionality to handle self recursive
function calls, i.e. whose SCC size is 1. Due to complexity of
ValueTracking in recursive calls with SCC size greater than 1, we bail
out in such cases.
