For one thing, because specifying one particular behavior would require
compilers to generate inefficient code even for cases with well-defined
behavior.

Suppose x is a 32-bit unsigned integer, and y has a value in the range
0..31 but the compiler is unable to prove it.  The current definition
(leaving x<<32 undefined) lets the compiler implement x<<y with a single
shift instruction.  Requiring x<<32 to yield some specific value would
require extra code for target systems where the shift instruction yields
a different result.

I'm not sure what you mean by that.  Type int, for example, has
a specific size and range for each implementation, but it varies
across implementations.  It's required to have a range of at least
-32767..+32767.
