cmd/asm: fix assembling return jump In RET instruction, the operand is the return jump's target, which should be put in Prog.To. Add an action "buildrundir" to the test driver, which builds (compile+assemble+link) the code in a directory and runs the resulting binary. Fixes #23838.

cmd/internal/obj: fix tail call in non-zero frame leaf function on MIPS and S390X A "RET f(SB)" wasn't assembled correctly in a leaf function with non-zero frame size. Follows CL 371034, for MIPS(32/64)(be/le) and S390X. Other architectures seem to do it right. Add a test.
