beam_utils: Simplify handling of 'return' to eliminate uncovered line
beam_jump: Clean up handling of labels before func_info
beam_expect: Correctly handle blocks with multiple allocs
v3_codegen: Don't confuse beam_validator
v3_codegen: Correct code generation for an error/1 call in a guard
beam_receive: Don't crash when encountering nonsensical code
