Change x64 size checks to not apply to x32. 
Rust contains various size checks conditional on target_arch = "x86_64",
but these checks were never intended to apply to
x86_64-unknown-linux-gnux32. Add target_pointer_width = "64" to the
conditions.

Rollup merge of #82176 - RalfJung:mir-fn-ptr-pretty, r=oli-obk 
fix MIR fn-ptr pretty-printing

An uninitialized function pointer would get printed as `{{uninit  fn()}` (notice the unbalanced parentheses), and a dangling fn ptr would ICE. This fixes both of that.

However, I have no idea how to add tests for this.

Also, I don't understand this MIR pretty-printing code. Somehow the print function `pretty_print_const_scalar` actually *returns* a transformed form of the const (but there is no doc comment explaining what is being returned); some match arms do `p!` while others do `self =`, and there's a wild mixture of `p!` and `write!`... all very mysterious and confusing.^^

like std or core via relative paths in modules
outside of lib.rs and main.rs.

Oliver Scherer 2d7ac728e4 Stop using the `const_eval` query for initializers of statics 
As a side effect, we now represent most promoteds as `ConstValue::Scalar` again. This is useful because all implict promoteds are just references anyway and most explicit promoteds are numeric arguments to `asm!` or SIMD instructions.
