Subject: [PATCH] allows cast int to bool/enum in VM (#22809)

Since they are integer types, by mean of allowing cast integer to enums
in VM, we can suppress some enum warnings in the stdlib in the unified
form, namely using a cast expression.

(cherry picked from commit 2cf214d6d46d11024e6420520e39eed779da284e)
