1. X86 fixes/changes

   a.  The old code generated for SETcc was completely wrong.
       The Intel optimization guide is VERY misleading.

2. ALPHA fixes/changes

   a.  Added the instructions LDBU, LDWU, STB, STW as per Fermin's suggestion.
   b.  Added a new mode byteWordLoadStores to the functor parameter to Alpha()
   c.  Added reassociation code for address computation.

1. X86 fixes/changes

   a.  x86Rewrite bug with MUL3 (found by Lal)
   b.  Added the instructions FSTS, FSTL

2. PA-RISC fixes/changes

   a.  B label should not be a delay slot candidate!  Why did this work?
   b.  ADDT(32, REG(32, r), LI n) now generates one instruction instead of two,
       as it should be.
   c.  The assembly syntax for fstds and fstdd was wrong.
   d.  Added the composite instruction COMICLR/LDO, which is the immediate
       operand variant of COMCLR/LDO.

3. Generic MLRISC

   a.  shuffle.sml rewritten to be slightly more efficient
   b.  DIV bug in mltree-simplify fixed (found by Fermin)

4. Register Allocator

   a.  I now release the interference graph earlier during spilling.
       May improve memory usage.

More assembly output problems involving the indexed addressing mode
on the x86 have been found and corrected. Thanks to Fermin Reig for the
fix.

The interface and implementation of the register allocator have been changed
slightly to accommodate the possibility to skip the register allocation
phases completely and go directly to memory allocation.  This is needed
for C-- use.

This fix only affects the x86 assembly output.

Fix up a few floating point bugs on the x86 that are discovered by Fermin.
Rewritten the Sethi-Ullman code.  Added new FP instructions to the x86,
including FIxxxx, FCOMxx, and FLDxx.
