* regcache.c (read_register_bytes): Failing to set register_valid
is not necessarily an error, if the register is a pseudo-register.
Some pseudo-registers are never marked as valid, so that they will
be read anew every time. Determining if a pseudo-register is valid
(or should be marked invalid) may be difficult, whereas just
recomputing it may be cheap.
