0.7.3.10: Fix the SIGILL with ev6 and later Alphas: icache needs flushing
after code objects are created e.g. by loading fasls
* Move sanctify-for-execution from *-vm.lisp to
compiler/target/sanctify.lisp, as *-vm is built too early to
call VOPs
* Add IMB to Alpha insts.lisp, and istream-memory-barrier VOP
that calls it.
* Create Alpha sanctify-for-execution function that calls said
new VOP
* Also flush icache after GC
* Double Alpha dynamic sizes to 256Mb: 128Mb is marginal to
rebuild SBCL
* Minor Config.ppc-linux cleanup
