[Analysis][EphemeralValuesCache][InlineCost] Ephemeral values caching for the CallAnalyzer (#130210)
This patch does two things:
1. It implements an ephemeral values cache analysis pass that collects the ephemeral values of a function and caches them for fast lookups. The collection of the ephemeral values is done lazily when the user calls `EphemeralValuesCache::ephValues()`.
2. It adds caching of ephemeral values using the `EphemeralValuesCache` to speed up `CallAnalyzer::analyze()`. Without caching this can take a long time to run in cases where the function contains a large number of `@llvm.assume()` calls and a large number of callsites. The time is spent in `collectEphemeralvalues()`.
