Devang Patel 4c758ea3e0 Large mechanical patch. 
s/ParamAttr/Attribute/g
s/PAList/AttrList/g
s/FnAttributeWithIndex/AttributeWithIndex/g
s/FnAttr/Attribute/g

This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

This requires corresponding changes in llvm-gcc and clang.

Evan Cheng 74c9ed91b0 With sse3 and when the source is a load or has multiple uses, favors movddup over shuffp*, pshufd, etc. Without sse3 or when the source is from a register, make use of movlhps

Dale Johannesen c50ada2f56 Accept 'inreg' attribute on x86 functions as 
meaning sse_regparm (i.e. float/double values go
in XMM0 instead of ST0).  Update documentation
to reflect reality.

Bill Wendling 7c31464a0b Refactor the constant folding code into it's own function. And call it from both 
the SelectionDAG and DAGCombiner code. The only functionality change is that now
the DAG combiner is performing the constant folding for these operations instead
of being a no-op.

This is *not* in response to a bug, so there isn't a testcase.
