ghc option "-ddump-splices" is cached and ignored in subsequent calls to "cabal build"

**Description**

The ghc option -ddump-splices is cached and subsequently ignored.

i.e. in a clean project, `cabal build --ghc-options=-ddump-splices` will enable the option for all subsequent calls to `cabal build`, whether or not the option is specified.

Likewise, an initial `cabal build` will cause later invocations of `cabal build --ghc-options=-ddump-splices` to ignore the option and continue to not dump splices.

**To Reproduce**

*(Sorry, don't have an easy reproducer at hand, though I think it should be easy to create one)*

**Expected behavior**

I would expect -ddump-splices to be treated as something like a verbosity flag. It should only affect the current run. It shouldn't affect recompilation: compiled things should stay compiled.
