edb05dfe48 Clarify the relationship between byval and readonly/ 
readnone.  Make clearer that readnone functions do not
dereference pointer arguments.  Do not use the highly
ambiguous "side-effects" in the readonly description
(since such functions can have control flow side-effects,
such as throwing an exception, or looping for ever).

meaning sse_regparm (i.e. float/double values go
in XMM0 instead of ST0).  Update documentation
to reflect reality.

f72fb679ef Extend the vcmp/fcmp LLVM IR instructions to take vectors as arguments 
and, if so, to return a vector of boolean as a result;

Extend the select LLVM IR instruction to allow you to specify a result
type which is a vector of boolean, in which case the result will be an
element-wise selection instead of choosing one vector or the other; and

Update LangRef.html to describe these changes.

This patch was contributed by Preston Gurd!

81a0c0b44e IR, bitcode reader, bitcode writer, and asmparser changes to 
insertvalue and extractvalue to use constant indices instead of
Value* indices. And begin updating LangRef.html.

There's definately more to come here, but I'm checking this 
basic support in now to make it available to people who are
interested.
