Gabe Black 3f67faec83 arch,dev,gpu-compute,sim: Rename isa_traits.hh page_size.hh.
The only thing left in isa_traits.hh are two constants, one for the
number of bytes in a page, and one for how far to shift an address to
get the page number. To make it clear that this is the only thing
isa_traits.hh should be used for from this point forward (until it is
entirely eliminated), this change renames it to the much less generic
page_size.hh.

Also, because isa_traits.hh used to have *much* more stuff in it, it was
included in a lot of places it didn't need to be. This change also
clears out all these legacy includes while updating the actually needed
ones to the new name.
