Don't suppress *all* Wanteds
Code in GHC.Tc.Errors.reportWanteds suppresses a Wanted if its
rewriters have unfilled coercion holes; see
Note [Wanteds rewrite Wanteds] in GHC.Tc.Types.Constraint.
But if we thereby suppress *all* errors that's really confusing,
and as #22707 shows, GHC goes on without even realising that the
program is broken. Disaster.
This MR arranges to un-suppress them all if they all get suppressed.
Close #22707

Check for platform support for JavaScript foreign imports
GHC was accepting `foreign import javascript` declarations
on non-JavaScript platforms. This adds a check so that these
are only supported on an platform that supports the JavaScript
calling convention.
Fixes #22774

rts: Statically assert alignment of Capability
In #22965 we noticed that changes in the size of `Capability` can result
in unsound behavior due to the `align` pragma claiming an alignment
which we don't in practice observe. Avoid this by statically asserting
that the size is a multiple of the alignment.

rts: Correctly align Capability allocations
Previously we failed to tell the C allocator that `Capability`s needed
to be aligned, resulting in #22965.
Fixes #22965.
Fixes #22975.

rts: Drop no-alignment special case for Windows
For reasons that aren't clear, we were previously not giving Capability
the same favorable alignment on Windows that we provided on other
platforms. Fix this.

constant folding: Correct type of decodeDouble_Int64 rule
The first argument is Int64# unconditionally, so we better produce
something of that type. This fixes a core lint error found in the ad
package.

ncg/aarch64: Handle MULTILINE_COMMENT identically as COMMENTs
Commit 7566fd9de38c67360c090f828923d41587af519c with the fix for #22798 was
incomplete as it failed to handle MULTILINE_COMMENT pseudo-instructions, and
didn't completly fix the compiler panics when compiling with `-fregs-graph`.
Fixes #23002
