This enables four different options in the compiler, described below. I also added enough masks to satisfy RTCc when running all GMs in both 8888 and gl configs. --- /RTCc - Detects when a value is assigned to a smaller data type and results in data loss. This happens even when casting. Masking is required to suppress this. /RTCs - Various stack-related checks, including uninitialized data (by initializing locals to a non-zero value), array bounds checking, and stack pointer corruption that can occur with a calling convention mismatch. /RTCu - Reports when a variable is used without having been initialized. Mostly redundant with compile-time checks. /guard:cf - This is more of a security option, that computes all possible targets for indirect calls at compile time, and verifies that those are the only targets reached at compile time. Also generates similar logic around switch statements that turn into jump tables.
