created interface to PETSc CG and a test file; appended an "export system" section to some apps and tests;  added method to copy PETSc Mat

- PETScExportOperatorMatrix.hpp contains a templated function that
  allows exporting an arbitrary operator to a file as matrix via PETSc.
- PETScSparseMatrix.hpp now contains a variant of the method
  applyDirichletBCSymmetrically() which does only modify the matrix
  itself, but not the RHS. So we need not pass any vectors.
- exportOperatorMatrix.cpp is a demo app that allows exporting some of
  our constant operators

Generated kernel benchmarks

See merge request terraneo/tinyhhg!224

Some potential kernel generation performance improvements

See merge request terraneo/tinyhhg!223

- split all edge fields into distinct pointers

- added const and RESTRICT to field ptrs

Code generation

See merge request terraneo/tinyhhg!222

- first 3D edge to edge apply kernel (first small tests indicate speedup of ~10)

- improved moving constants before loops optimization (much less duplicate code)

- fixed sum splitting for some kernels

Upgrade compiler for benchmarks
