rts: Fix EINTR check in timerfd ticker

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.

rts/RtsFlags: Refactor size parsing

This makes a number of improvements mentioned in #20201:

 * fail if the argument cannot be parsed as a number (`-Mturtles`)
 * fail if an unrecognized unit is given (e.g. `-M1x`)

Introduce GHC.Tc.Plugin.lookupTHName

This makes it significantly more convenient (and less
GHC-version-dependent) to resolve a template-haskell name into a GHC
Name.

As proposed in #24741.

X86 NCG: allow VXOR at scalar floating-point types

The NCG can emit VXOR instructions at scalar floating-point types,
but the pretty-printer would panic instead of emitting the appropriate
VXORPS/VXORPD instructions. This patch rectifies that oversight.

Fixes #25455

rts: Fix platform-dependent pointer casts

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.
