During bottom up fast-isel, instructions emitted to materalize registers are at top of basic block and do not have debug location. This may misguide debugger while entering the basic block and sometimes debugger provides semi useful view of current location to developer by picking up previous known location as current location. Assign a sensible location to the first instruction in a basic block, if it does not have one location derived from source file, so that debugger can provide meaningful user experience to developers in edge cases.

Intern all RecTy subclass instances to avoid duplicates.

Make all of the RecTy constructors private, and use get() factory

ListTy instance pointers are stored in the element RecTy instance.
BitsRecTy instance pointers, one per length, are stored in a static vector.
Also unique DefInit instances. A Record has a unique DefInit which
has a unique RecordRecTy instance.
This saves some 200k-300k RecTy allocations when parsing ARM.td. It

Introduce the 'makeArrayRef(...)' family of functions, which fills a similar role for ArrayRef<> as std::make_pair() fills for std::pair<>: they return the right instantiation of ArrayRef<T> based on the types of the parameters.
...
They mostly mirror the ArrayRef constructors, with two exceptions:
* There's no function mirroring the default constructor because it wouldn't have any parameters to deduce the right ArrayRef<T> from.
* There's an explicit SmallVector<T> overload in addition to the SmallVectorImpl<T> overload. Without it, the single-element overload would try to create an ArrayRef<Smallvector<T> > because it's a better match according to the overloading rules. (And both overloads are used in the current tree, so neither is redundant)
