Scott McMurray 2c6ec51564 Update __rust_[rd]ealloc to take NonNull<u8> instead of *mut u8 
Passing null to it is [already UB](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2024&gist=8dcd25a549c11de72adc94a668277779) anyway.

The goal of this directory is to track the quality of MIR that is given to codegen in a standard -O configuration.

As such, feel free to --bless whatever changes you get here, so long as doing so doesn't add substantially more MIR.
