rts, tests: limit thread name length to 15 bytes

On Linux, `pthread_setname_np` (or rather, the kernel) only allows for
thread names up to 16 bytes, including the terminating null byte.

This commit adds a note pointing this out in `createOSThread`, and fixes
up two instances where a thread name of more than 15 characters long was
used (in the RTS, and in a test-case).

Store bootstrap_llvm_target and use it to set LlvmTarget in bindists

This mirrors some existing logic for the bootstrap_target which
influences how TargetPlatform is set.

As described on #21970 not storing this led to `LlvmTarget` being set incorrectly
and hence the wrong `--target` flag being passed to the C compiler.

Towards #21970

Check for FP_LD_NO_FIXUP_CHAINS in installation configure script

Otherwise, when installing from a bindist the C flag isn't passed to the
C compiler.

This completes the fix for #22429

Add PrimCallConv support to GHCi

This adds support for calling Cmm code from bytecode using the native
calling convention, allowing modules that use `foreign import prim`
to be loaded and debugged in GHCi.

This patch introduces a new `PRIMCALL` bytecode instruction and
a helper stack frame `stg_primcall`. The code is based on the
existing functionality for dealing with unboxed tuples in bytecode,
which has been generalised to handle arbitrary calls.

Fixes #22051
