tblgen needs to become smarter about tglobaladdr nodes and bigger patterns

li r2, lo16(L_x$non_lazy_ptr)
lis r3, ha16(L_x$non_lazy_ptr)

use -enable-ia64-dag-isel to turn this on
TODO: delete lowering stuff from the pattern isel
: get operations on predicate bits working
: get other bits of pseudocode going
: use sampo's mulh/mull-using divide-by-constant magic
: *so* many patterns ("extr", "tbit" and "dep" will be fun :)
: add FP
: add a JIT!
: get it working 100%
in short: this'll be happier in a couple of weeks, but it's here now so
the tester can make me feel guilty sooner.
OTHER: there are a couple of fixes to the pattern isel, in particular
making the linker happy with big blobs of fun like pypy.
