A recent change added UNSPEC to the CCMP patterns to stop combine optimizing
the immediate in a rare case. This requires a fix to the CCMP cost
calculation as the CCMP instruction with unspec is no longer recognized.

compiler: Don't crash on erroneous array return types.
Another issue with erroneous array types. When an erroneous array
type is in a function's signature, particularly the return type, we
must guarantee that type is changed into an error type. Otherwise,
any operations that work on arrays and slices will crash when applied
to the erroneous array return type.

compiler: Avoid knock-on errors with impossibly large types.
The gofrontend asks the backend compiler for the architecture
appropriate size of a given type. For array types, it is possible
to construct a type too large to fit on the machine. This patch does
two things: 1. When an impossibly large type is encountered, we mark
the type as erroneous and later calls to discover the size of that
type are short-circuited. 2. When generating the GC symbol data for
an impossibly large array of arrays, we avoid generating symbol data
as soon as we find an array that is too large to be expressed.
