{tools}[gcccuda/2020b] ROCm v4.0.1

[boegel]

(created using eb --new-pr)

Based on https://github.com/cschpc/lumi/blob/main/rocm/rocm_installation.sh by @gmarkomanolis (doesn't include hipify-clang, that should probably be a separate installation?)

WIP, because:

• Need to figure out versioning of the components: most are rocm-4.0.0, some are rocm-4.0.1, what should be the top-level version?
• Currently it's one big "flat" installation, while it's recommended to install things in proper subdirectory (like the LLVM stuff into <installdir>/llvm)
• What should we check for in the sanity check in terms of files/directories/commands?
• CUDA compute capabilities should not be hardcoded
• Maybe it's better to have an easyblock for this whole mess, so we can just have a clean list of components (and checksums) here? That would also make it easier to do the same installation for AMD GPU systems...

Hipify-clang from here: https://github.com/ROCm-Developer-Tools/HIPIFY

I will add instructions soon.

For hipify-clang:

• You have in the PATH the bin directory of the installed LLVM
  git clone -b rocm-4.0.0 https://github.com/ROCm-Developer-Tools/HIPIFY.git
cd HIPIFY
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/path_rocm/hip/bin/ ..
make
make install
