When `poll` failed we previously checked that `errno == -EINTR` to
silence the failure warning. However, this is wrong as `errno` values
are generally not negated error codes (in contrast to many system call
results, which is likely what the original author had in mind).
Fixes #25477.

but the pretty-printer would panic instead of emitting the appropriate
VXORPS/VXORPD instructions. This patch rectifies that oversight.

Previously we had unnecessary (and incorrect) platform-dependent casts
to turn `OSThreadIds`s into a integer. We now just uniformly cast first
to a `uintptr_t` (which is always safe, regardless of whether
`OSThreadId` is a pointer), and then cast to the desired integral type.
This fixes a warning on musl platforms.
