Fix -freg-graphs for FP and AARch64 NCG (#24941).

It seems we reserve 8 registers instead of four for global regs
based on the layout in Note [AArch64 Register assignments].

I'm not sure it's neccesary, but for now we just accept this state of
affairs and simple update -fregs-graph to account for this.

Linker: use m32 allocator for sections when NEED_PLT (#24432)

Use M32 allocator to avoid fragmentation when allocating ELF sections.
We already did this when NEED_PLT was undefined. Failing to do this led
to relocations impossible to fulfil (#24432).

Fixes #24930.

GHCi interpreter: Tag constructor closures when possible.

When evaluating PUSH_G try to tag the reference we are pushing if it's a
constructor. This is potentially helpful for performance and required to
fix #24870.

Add missing parenthesizePat in cvtp

We need to ensure that the output of `cvtp` is parenthesized (at precedence
`sigPrec`) so that any pattern signatures with a surrounding pattern signature
can parse correctly.

Fixes #24837.

compiler: Fingerprint -fwrite-if-simplified-core

We need to recompile if this flag is changed because later modules might depend on the
simplified core for this module if -fprefer-bytecode is enabled.

Fixes #24656

Don't depend on registerPackage function in Cabal

More recent versions of Cabal modify the behaviour of libAbiHash which
breaks our usage of registerPackage.

It is simpler to inline the part of registerPackage that we need and
avoid any additional dependency and complication using the higher-level
function introduces.
