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.

This reverts commit 009f51e43f.
Reason for revert: unintentional header consequences in Chromium... will reland after fixing Chromium

Originally we wrote this in C++14 constexpr,
but because this is used from public headers, we can't use
C++14 yet. Now a somewhat sillier looking C++11 version.
All the old tests still pass, and one new added.
Updated the comments a bit for correctness and readability.

This reverts commit b82c3d6ff2.
Reason for revert: SkTFitsIn makes its way into public headers via SkTo<T>, so it cannot use C++14isms.
