Rollup merge of #136235 - oli-obk:transmuty-pat-tys, r=RalfJung

Pretty print pattern type values with transmute if they don't satisfy their pattern

Instead of printing `0_u32 is 1..`, we now print the default fallback rendering that we also use for invalid bools, chars, ...: `{transmute(0x00000000): (u32) is 1..=}`.

These cases can occur in mir dumps when const prop propagates a constant across a safety check that would prevent the actually UB value from existing. That's fine though, as it's dead code and we always need to allow UB in dead code.

follow-up to rust-lang/rust#136176

cc ``@compiler-errors`` ``@scottmcm``

r? ``@RalfJung`` because of the interpreter changes
