Fariborz Jahanian d7aa9d8a63 Patch to gives an error that at least points users in the direction of the error, rather 
than an error about incompatible types. Patch by Sean Hunt.

Chris Lattner 63ffdc748a temporarily remove these tests, as they are breaking in the buildbot, 
Eric, please investigate.

Chris Lattner c77d24b792 make instcombine only rewrite a chain of computation 
(eliminating some extends) if the new type of the
computation is legal or if both the source and dest
are illegal.  This prevents instcombine from changing big
chains of computation into i64 on 32-bit targets for 
example.

Chris Lattner 6fafd70c1e all targets should be required to declare legal integer types. My plan to 
make it optional doesn't work out.  If you don't want to specify this, don't
specify a TD string at all.

Chris Lattner a381effe72 add the ability for TargetData to return information about legal integer 
datatypes on a given CPU.  This is intended to allow instcombine and other
transformations to avoid converting big sequences of operations to an
inconvenient width, and will help clean up after SRoA.  See also "Adding 
legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451.

Comments welcome.

Jeffrey Yasskin db5f24ce77 Make the need-stub variables accurate and consistent. In the case of 
MachineRelocations, "stub" always refers to a far-call stub or a
load-a-faraway-global stub, so this patch adds "Far" to the term. (Other stubs
are used for lazy compilation and dlsym address replacement.) The variable was
also inconsistent between the positive and negative sense, and the positive
sense ("NeedStub") was more demanding than is accurate (since a nearby-enough
function can be called directly even if the platform often requires a stub).
Since the negative sense causes double-negatives, I switched to
"MayNeedFarStub" globally.

of movhps as the constraint.  Changes optimizations so
update testcases as appropriate as well.

Chris Lattner 5ff7f5672e reapply 86289, 86278, 86270, 86267, 86266 & 86264 plus a fix 
(making pred factoring only happen if threading is guaranteed
to be successful).

This now survives an X86-64 bootstrap of llvm-gcc.
