Be more careful about merge blocks during loop inversion (#3136)

* fix block eater

* Be more careful about merge blocks during loop inversion

* Restrict loop inversion to loops without continue jumps

* Remove multiple back-edges from loops for SPIR-V

* Wiggle cross compile test output

* Make loop-inversion more conservative

* Allow loops on false side in cfg normalization

* Do not set loop continue block during inversion

* Add loop inversion test to failing test list for spirv

* Simplify single use continue blocks in spirv legalization

* wobble expected failure list
