Just out of curiosity, I checked the  x *= 17; statement with
SAS/C 5.10a, basically it does do an lsl #4 and an add #1, as
long as the argument is not a short when compiled without the -w
option.  If the argument is a short and 32 bit ints are the default,
the compiler uses a mul #$11 rather than the lsl, add.  In all other
cases it seems to do an lsl, add sequence.

I guess compilers are getting smarter.
