WIP Implementation of the LLVM OpenMP runtime.

Added initial implementation of the LLVM OpenMP runtime.

Added

New KMP runtime.
Runtime testing infrastructure.
Automated benchmark running and plotting.
Embedded Template Library.
Clangd and clang-tidy configs.
Banshee config.

Changed

Snitch trace now includes the SP to aid in building better tracevis.
The tracevis target now depends on the trace target and uses uses -cf.
omp runtime directory renamed to gomp.
Link with lld when using clang.

Fixed

Fix building verilator on newer clang and gcc versions.
Fix tracing targets missing some harts.
Clang warnings about the .comment section.

[software] [software] - Don't use 64 bit pointers in loops (not supported yet) [software] - Run both tests

- Implement main warpper for gomp so that apps and tests can be shared across implementations

- Add runner.py for code reuse

- copyPrivate is now a method of the team class - team can now be started slightly faster when its the only one - atomics are removed where they were not needed
