Description

I could not find a way to pass options to HPC (as documented in https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/profiling.html#hpc-report).

The one I am particularly interested in is --xml-output to be able to parse coverage (and hopefully convert it into SonarQube-compatible code coverage later). I could not find an equivalent in stack, stack hpc or stack hpc report documentation/help.

Contributor guide

Research direction
Investigate how stack invokes HPC and where command line arguments are passed. Add a new flag to forward options to HPC, such as hpc options.
