compiler: support using int flags in field conditions
Commit ed571339c6ff ("pkg/compiler: support if[expr] attributes") added
support for conditional fields in structs and unions. Conditions however
cannot refer to flags, as in the following example:
struct {
f0 flags[some_flags, int32]
f1 int32 (if[value[f0] & FLAG1])
} [packed]
It will fail to compile with:
flags does not refer to an integer
This commit adds support for that syntax.
