3fdc97d460 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 -O0style of build.

f0469f0376 just some random hacking - calls (particularly indirect) need a lot of
love (especially with -sched=simple)

cf11aefc91 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.

c2c2e353ee 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

6314b5fc35 FORTRAN!!! :( and other similarly unfortunate things mean that on ia64
one sometimes needs to pass FP args in both FP *and* integer registers.

9c1cbbe5d1 add some FP stuff, some mix.* stuff, and constant pool support to the
DAG instruction selector, which should be destroyed one day (in the pattern
isel also) since ia64 can pack any constant in the instruction stream

251185e626 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.

d3b3d07c41 Add FP versions of the binary operators, keeping the int and fp worlds seperate.
Though I have done extensive testing, it is possible that this will break
things in configs I can't test.  Please let me know if this causes a problem
and I'll fix it ASAP.

a31708e6b3 Change ConstantPoolSDNode to actually hold the Constant itself instead of
putting it into the constant pool.  This allows the isel machinery to
create constants that it will end up deciding are not needed, without them
ending up in the resultant function constant pool.
