[PATCH] Coverage mapping: Don't map implicit casts and modify "ignore if not extended" flag semantics

[Alex L]

It's ensuring that macros like `define N 1024` don't create mapping regions
when the integer literal
is implicitly converted. It also makes sure that literals in ternary
conditional create mapping regions
- e.g. there will be a mapping region for 1 and 0 in `cond? 1 : 0` .
