Move the spaces around a bit.

compiler/x86/parms.lisp:
o Move the linkage space to #x30000000, which is in the gap between
  the static space and the control stack.

lisp/x86-validate.h:
o Document the memory map for Solaris.
o Set the altstack to the end of the control stack.

64 *
65 * (Note: 0x58000000 allows us to run on a Linux system on an AMD
66 * x86-64. Hence we have a gap of unused memory starting at
67 * 0x48000000.)
