Our aliasification logic would previously turn builtin LLVM variables
into aliases, which apparently confuses LLVM. This manifested in
initializers failing to be emitted, resulting in many profiling failures
with the LLVM backend.
Fixes #22019.

This is an improvement to HPC authored by Richard Wallace
(https://github.com/purefn) and myself. I have received permission from
him to attempt to upstream it. This improvement was originally
implemented as a patch to HPC via input-output-hk/haskell.nix:
https://github.com/input-output-hk/haskell.nix/pull/1464
Paraphrasing Richard, HPC currently requires all inputs as command line arguments.
With large projects this can result in an argument list too long error.
I have only seen this error in Nix, but I assume it can occur is a plain Unix environment.
This MR adds the standard response file syntax support to HPC. For
example you can now pass a file to the command line which contains the
arguments.
```
hpc @response_file_1 @response_file_2 ...
The contents of a Response File must have this format:
COMMAND ...
example:
report my_library.tix --include=ModuleA --include=ModuleB
```
Updates hpc submodule

The -x option is used to manually specify which phase a file should be
started to be compiled from (even if it lacks the correct extension). I
just failed to implement this when refactoring the driver.
In particular Cabal calls GHC with `-E -cpp -x hs Foo.cpphs` to
preprocess source files using GHC.
I added a test to exercise this case.

Since 2011 the object-joining implementation has had a hack to pass

who expect objects to have valid build-ids. Remove it.

I had assumed that wrappers were not inlined in interactive mode.
Meaning we would always execute the compiled wrapper which properly
takes care of upholding the strict field invariant.
This turned out to be wrong. So instead we now run tag inference even
when we generate bytecode. In that case only for correctness not
performance reasons although it will be still beneficial for runtime
in some cases.
I further fixed a bug where GHCi didn't tag nullary constructors
properly when used as arguments. Which caused segfaults when calling
into compiled functions which expect the strict field invariant to
be upheld.
