Using const is orthogonal to guidelines on using auto& and auto*.

[C++11] Replacing ObjCMethodDecl iterators param_begin() and param_end() with iterator_range params(). Updating all of the usages of the iterators with range-based for loops.

A freebsd issue with rm prevents '[g]make clean' from working if $(DSYM)
is empty (fts_open(3) fails if passed an empty argument).

To work around this, simplify the clean target by using three separate
rm invocations: one for the common files, one for the case of non-empty
$(DYLIB_NAME), and one for non-empty $(DSYM).

Issue diagnosed (and reported to FreeBSD) by John Wolfe.

[C++11] Adding an iterator_range accessor for parameter declarations to the CaptureDecl class; however, the only usage of the iterators cannot be converted to using the range yet. This change is for consistency with other Decls exposing parameters.

The target was marking SIGN_EXTEND as Custom because it wanted to optimize
certain sign-extended shifts.  In all other respects the extension is Legal,
so it'd be better to do the optimization in PerformDAGCombine instead.

No functional change intended.

This helps the instruction selector to lower an i64 * i64 -> i128
multiplication into a single instruction on targets which support it.

Sequences of insertelement/extractelements are sometimes used to build
vectorsr; this code tries to put them back together into shuffles, but
could only produce a completely uniform shuffle types (<N x T> from two
<N x T> sources).

This should allow shuffles with different numbers of elements on the
input and output sides as well.
