  It was a subset of this patchset.

Feature Description

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.

I also made a change so that we test fp (alias of x8 or s0; I forgot to add this to the test).
