[MemDep] Use EarliestEscapeInfo (#69727)

Use BatchAA with EarliestEscapeInfo instead of callCapturesBefore() in
MemDepAnalysis. The advantage of this is that it will also take
not-captured-before information into account for non-calls (see
test_store_before_capture for a representative example), and that this
is a cached analysis. The disadvantage is that EII is slightly less
precise than full CapturedBefore analysis.

In practice the impact is positive, with gvn.NumGVNLoad going from 22022
to 22808 on test-suite. 

The impact to compile-time is also positive, mainly in the ThinLTO
configuration.
