Reverting r208106 to reapply r208065 with a fix for the regression. The
issue was that the enum tried to be built even if the declaration hadn't
been constructed for debug info - presenting problems for enum templates
and typedefs of enums with names for linkage purposes.
Original commit message:
This regressed a little further 208055 though it was already a little
broken.
While the requiresCompleteType optimization should be implemented here.
Future (possibly near future) work.

BugReport doesn't take ownership of the bug type, so let the checker own the
the bug type. (Requires making the bug type mutable, which is icky, but which
is also what other checkers do.)

(I tried converting StateMapsArray to a vector<unique_ptr> and changing the
types of getInfo() and addInfo() to take unique_ptrs. This mostly worked,
except for the three-argument form of addInfo() which I found confusing enough
that I went with this simpler fix for now.)

Before this patch, the backend always emitted a store+load sequence to
bitconvert from f64 to i64 the input operand of a ISD::BITCAST dag node that
performed a bitconvert from type MVT::f64 to type MVT::v2i32. The resulting
i64 node was then used to build a v2i32 vector.
With this patch, the backend now produces a cheaper SCALAR_TO_VECTOR from
MVT::f64 to MVT::v2f64. That SCALAR_TO_VECTOR is then followed by a "free"
bitcast to type MVT::v4i32. The elements of the resulting
v4i32 are then extracted to build a v2i32 vector (which is illegal and
therefore promoted to MVT::v2i64).
This is in general cheaper than emitting a stack store+load sequence
to bitconvert the operand from type f64 to type i64.

This patch implements the infrastructure to use named register constructs in
programs that need access to specific registers (bare metal, kernels, etc).
So far, only the stack pointer is supported as a technology preview, but as it
is, the intrinsic can already support all non-allocatable registers from any
architecture.

An alias has the address of what it points to, so it also has the same
alignment.
This allows a few optimizations to see past aliases for free.

fall back to the normal path without a cpu. While doing this fix
llc to just exit when we don't have a module to process instead of
asserting.

Before:
goog.scope(function() {
var x = a.b;
var y = c.d;
}); // goog.scope
After:
goog.scope(function() {
var x = a.b;
var y = c.d;
}); // goog.scope

Obviously we can't expect the two backends to produce identical diagnostics,
since what's possible depends quite a bit on how the .td files are structured.
I think the ARM64 diagnostics are basically of the same quality in all the
changed cases, so I've split the CHECK lines.
