GHCi debugger: drop record name spaces for Ids

When binding new local variables at a breakpoint, we should create
Ids with variable namespace, and not record field namespace. Otherwise
the rest of the compiler falls over because the IdDetails are wrong.

Fixes #25109

Support for rubbish dynamic literals was added in #24664. This patch
does the same for static literals.

compiler: Store ForeignStubs and foreign C files in interfaces

This data is used alongside Core bindings to reconstruct intermediate
build products when linking Template Haskell splices with bytecode.

Since foreign stubs and files are generated in the pipeline, they were
lost with only Core bindings stored in interfaces.

The interface codec type `IfaceForeign` contains a simplified
representation of `ForeignStubs` and the set of foreign sources that
were manually added by the user.

When the backend phase writes an interface, `mkFullIface` calls
`encodeIfaceForeign` to read foreign source file contents and assemble
`IfaceForeign`.

After the recompilation status check of an upstream module,
`initWholeCoreBindings` calls `decodeIfaceForeign` to restore
`ForeignStubs` and write the contents of foreign sources to the file
system as temporary files.
The restored foreign inputs are then processed by `hscInteractive` in
the same manner as in a regular pipeline.

When linking the stub objects for splices, they are excluded from suffix
adjustment for the interpreter way through a new flag in `Unlinked`.

For details about these processes, please consult Note [Foreign stubs
and TH bytecode linking].

git: remove a.out and include it in .gitignore

a.out is a configure script byproduct. It was mistakenly checked into
the tree in !13118. This patch removes it, and include it in
.gitignore to prevent a similar error in the future.

testsuite: Add support to capture performance metrics via 'perf'

Performance metrics collected via 'perf' can be more accurate for
run-time performance than GHC's rts, due to the usage of hardware
counters.

We allow performance tests to also record PMU events according to 'perf
list'.
