Introduce -fprof-callers flag

This introducing a new compiler flag to provide a convenient way to
introduce profiler cost-centers on all occurrences of the named
identifier.

Closes #18566.

Move Plugins into HscEnv (#17957)

Loaded plugins have nothing to do in DynFlags so this patch moves them
into HscEnv (session state).

"DynFlags plugins" become "Driver plugins" to still be able to register
static plugins.

Bump haddock submodule

Don't initialize plugins in the Core2Core pipeline

Some plugins can be added via TH (cf addCorePlugin). Initialize them in
the driver instead of in the Core2Core pipeline.

Add regression test for #10504

This issue was fixed at some point between GHC 8.0 and 8.2. Let's add a
regression test to ensure that it stays fixed.

Fixes #10504.

dwarf: Apply info table offset consistently

Previously we failed to apply the info table offset to the aranges and
DIEs, meaning that we often failed to unwind in gdb. For some reason
this only seemed to manifest in the RTS's Cmm closures. Nevertheless,
now we can unwind completely up to `main`

[Sized Cmm] properly retain sizes.

This replaces all Word<N> = W<N># Word# and Int<N> = I<N># Int#  with
Word<N> = W<N># Word<N># and Int<N> = I<N># Int<N>#, thus providing us
with properly sized primitives in the codegenerator instead of pretending
they are all full machine words.

This came up when implementing darwinpcs for arm64.  The darwinpcs reqires
us to pack function argugments in excess of registers on the stack.  While
most procedure call standards (pcs) assume arguments are just passed in
8 byte slots; and thus the caller does not know the exact signature to make
the call, darwinpcs requires us to adhere to the prototype, and thus have
the correct sizes.  If we specify CInt in the FFI call, it should correspond
to the C int, and not just be Word sized, when it's only half the size.

This does change the expected output of T16402 but the new result is no
less correct as it eliminates the narrowing (instead of the `and` as was
previously done).

Bumps the array, bytestring, text, and binary submodules.
