New Issue: CHPL_NO_CODEGEN is confused

16819, “vasslitvinov”, “CHPL_NO_CODEGEN is confused”, “2020-12-05T02:01:06Z”

The meaning of CHPL_NO_CODEGEN is reversed:

CHPL_NO_CODEGEN=0 chpl .....    # skips codegen
CHPL_NO_CODEGEN=1 chpl .....    # runs codegen

I suggest renaming CHPL_NO_CODEGEN to CHPL_CODEGEN.
While there, rename no_codegen in the compiler to fCodegen or somesuch.
