gitlab-ci: Don't use .full-ci to run test-primops

test-primops depends upon the existence of validate jobs, yet these do
not exist in the context of nightly jobs, which .full-ci includes.

ghc-toolchain: Parse i686 triples

This is a moniker used for later 32-bit x86 implementations
(Pentium Pro and later).

Fixes #25691.

perf: Replace uses of genericLength with strictGenericLength

genericLength is a recursive function and marked NOINLINE. It is not
going to specialise. In profiles, it can be seen that 3% of total compilation
time when computing bytecode is spend calling this non-specialised
function.

In addition, we can simplify `addListToSS` to avoid traversing the input
list twice and also allocating an intermediate list (after the call to
reverse).

Overall these changes reduce the time spend in 'assembleBCOs' from 5.61s
to 3.88s. Allocations drop from 8GB to 5.3G.

Fixes #25706

perf: nameToCLabel: Directly manipulate ByteString rather than going via strings

`nameToCLabel` is called from `lookupHsSymbol` many times during
bytecode linking. We can save a lot of allocations and time by directly
manipulating the bytestrings rather than going via intermediate lists.

Before: 2GB allocation, 1.11s
After: 260MB allocation, 375ms

Fixes #25719
