a88628cd72 Now that the profitable bits of EnableFullLoadPRE have been enabled by default, rip out the remainder. 
Anyone interested in more general PRE would be better served by implementing it separately, to get real
anticipation calculation, etc.

c14a1eda84 Massive rewrite of MMX: 
The x86_mmx type is used for MMX intrinsics, parameters and
return values where these use MMX registers, and is also
supported in load, store, and bitcast.

Only the above operations generate MMX instructions, and optimizations
do not operate on or produce MMX intrinsics. 

MMX-sized vectors <2 x i32> etc. are lowered to XMM or split into
smaller pieces.  Optimizations may occur on these forms and the
result casted back to x86_mmx, provided the result feeds into a
previous existing x86_mmx operation.

The point of all this is prevent optimizations from introducing
MMX operations, which is unsafe due to the EMMS problem.

5adba2c2ff We do want to allow LoadPRE to perform LICM-like transformations: we already consider PHI nodes to be negligible for 
code size (making this transform code size neutral), and it allows us to hoist values out of loops, which is always
a good thing.

should use a section instead.
