Leo Yan 9a4e47ef98 perf parse-regs: Introduce a weak function arch__sample_reg_masks()
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.
