Chen Pei 0b26b346a8 perf riscv: Add perf_regs_load and enable the dwarf unwind test 
riscv has no arch level perf test: tests/builtin-test.c only picks up
arch_tests[] for x86, arm64 and powerpc64, tests/Build only builds the
generic dwarf unwind test driver for x86, arm, arm64 and powerpc, and
arch/riscv/tests/ did not exist. "Test dwarf unwind" was therefore never
registered on riscv, even though DWARF is the only reliable way to walk a
riscv user stack -- the arch callchain code walks frame pointers only --
and both unwinders already support riscv, elfutils libdw generically and
libunwind through util/libunwind-arch/libunwind-riscv.c.

Add perf_regs_load() and the arch unwind sample helper modelled on the
arm64 ones, and wire riscv into the two gates. The x1..x31 slots of enum
perf_event_riscv_regs match the hardware registers one to one, and
PERF_REG_RISCV_PC is filled with ra so that unwinding starts at the
caller.
