5cefc5e64d whatever. Intermediate patch to see what breaks. Seems ok.

df2e425f2a Add a new option to indicate we want the code generator to emit code quickly, 
not spending tons of time microoptimizing it.  This is useful for an -O0
style of build.

00873ebc1f just some random hacking - calls (particularly indirect) need a lot of 
love (especially with -sched=simple)

ae232e7a10 Add the necessary support to the ISel to allow targets to codegen the new 
alignment information appropriately.  Includes code for PowerPC to support
fixed-size allocas with alignment larger than the stack.  Support for
arbitrarily aligned dynamic allocas coming soon.

21687e8f63 ask for 16-byte aligned jmpbufs. This should unbreak C++ on IA64 (and 
a bunch of other things) but is currently ignored by the code
generator.

764fe71e12 oops, forgot to load GP for indirect calls, though the old code now commented 
out failed (e.g. methcall) - now the code compiles, though it's not quite
right just yet (tm) ;)

would fix this but it's 3am! :O

dc9549b52c FORTRAN!!! :( and other similarly unfortunate things mean that on ia64 
one sometimes needs to pass FP args in both FP *and* integer registers.

f2db9b88da DAG->DAG instruction selection for ia64! "hello world" works, not much else. 
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.
