RISC-V: Give stack slots same align as XLEN.
For riscv64-linux target, fixes
FAIL: gdb.base/gnu_vector.exp: call add_many_charvecs
Ensure that stack slots are always the same alignment as XLEN by rounding
up arg align to xlen.
gdb/
* riscv-tdep.c (riscv_call_arg_scalar_int): Use std::min when
setting len. New local align, set to max of arg align and xlen,
and pass to first riscv_assign_stack_location call.
