Rollup merge of #94343 - RalfJung:fn-ptr, r=oli-obk
Miri fn ptr check: don't use conservative null check In https://github.com/rust-lang/rust/pull/94270 I used the wrong NULL check for function pointers: `memory.ptr_may_be_null` is conservative even on machines that support ptr-to-int casts, leading to false errors in Miri. This fixes that problem, and also replaces that foot-fun of a method with `scalar_may_be_null` which is never unnecessarily conservative. r? `@oli-obk`
