Daniel Morsing	85ce3c7241	cmd/gc: mark broken type declarations as broken. ... This fixes a spurious 'invalid recursive type' error, and stops the compiler from emitting errors on uses of the invalid type. Fixes #3766.

Nigel Tao	251199c430	cmd/8g: roll back the small integer constant optimizations introduced ... in 13416:67c0b8c8fb29 "faster code, mainly for rotate" [1]. The codegen can run out of registers if there are too many small-int arithmetic ops. An alternative approach is to copy 6g's sbop/abop codegen to 8g, but this change is less risky. Fixes #3835.
