  It was a subset of this patchset.

Feature Description (Merge 1)

Although it had csr-dw-regnums.d to test DWARF register numbers for CSRs, it didn't have DWARF register number test for GPRs/FPRs. So, this patchset adds it.

The reason I split this (from vector register patchset) is these register numbers for GPRs/FPRs are widely accepted already and adding this test first makes possible to completely split vector register patchset and the DWARF register number test itself.

We also have to test fp (alias of x8 or s0; I forgot to add this to the test).
