Rollup merge of #88668 - hvdijk:x32, r=joshtriplett

Change more x64 size checks to not apply to x32.

Commit 95e096d6 changed a bunch of size checks already, but more have
been added, so this fixes the new ones the same way: the various size
checks that are conditional on target_arch = "x86_64" were not intended
to apply to x86_64-unknown-linux-gnux32, so add
target_pointer_width = "64" to the conditions.
