Every architecture can provide a register list for sampling. If an architecture doesn't support register sampling, it won't define the data structure 'sample_reg_masks'. Consequently, any code using this structure must be protected by the macro 'HAVE_PERF_REGS_SUPPORT'. This patch defines a weak function, arch__sample_reg_masks(), which will be replaced by an architecture-defined function for returning the architecture's register list. With this refactoring, the function always exists, the condition checking for 'HAVE_PERF_REGS_SUPPORT' is not needed anymore, so remove it.
