Before the prior commit, the maximum comptime recursion depth on my
system was 4062. After the prior commit, it decreased to 2854. This
commit increases the compiler's stack size enough so that the recursion
depth limit is no less than it was before the `Sema.analyzeCall`
rewrite, preventing this from being a breaking change. Specifically,
this stack size increases my observed maximum comptime recursion depth
to 4105.
