in #77413 it was noted that MIR dumps in our test suite somtimes differ between little and big endian, making our test suite fail on big endian. This is just about MIR pretty printing.

All that needs to be done is to pull out

into a separate function that returns true if the verbose printing should be used and then make it recurse on ty::Tuple and ty::Array elements.

You can then run rerun tests separately for 64bit and 32bit (the latter via e.g. --target i686-unknown-linux-gnu)
