runtime: fix racefuncenter argument corruption. Revision 6a88e1893941 corrupts the argument to racefuncenter by pushing the data block pointer to the stack. Fixes #4885.

runtime: record argument size in assembly functions I have not done the system call stubs in sys_*.s. I hope to avoid that, because those do not block, so those frames will not appear in stack traces during garbage collection.
