If a ParmVarDecl's default argument is a CXXExprWithTemporaries, return the underlying expr instead. Add getNumDefaultArgTemporaries and getDefaultArgTemporary which returns the temporaries a default arg creates.

For hi/odd of an odd-length vector, the last component is undefined.  Since
we shuffle with an undef vector, no CodeGen needs to change to support this.

1. Use std::equal instead of reinventing it.
2. don't run dtors in destroy_range if element is pod-like.
3. Use isPodLike to decide between memcpy/uninitialized_copy 
   instead of is_class.  isPodLike is more generous in some cases.

Remove isPod() from DenseMapInfo, splitting it out to its own
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

Checks that the code generated by 'tblgen --emit-llvmc' can be actually

- forward_transformed_value didn't work with non-list arguments
- cl::ZeroOrOne is now called cl::Optional

1. Only perform (zext (shl (zext x), y)) -> (shl (zext x), y) when y is a constant. This makes sure it remove at least one zest.
2. If the shift is a left shift, make sure the original shift cannot shift out bits.
