The x86 user pointer validation changes made me look at compiler output
a lot, and the wrong indentation for the ".popsection" in the generated

This implements the runtime constant infrastructure for x86, allowing
the dcache d_hash() function to be generated using as a constant for
hash table address followed by shift by a constant of the hash index.
