To write out an LZW dictionary entry each byte
requires two table lookups, one of which must complete
before the next lookup can begin. This change makes it
possible to write up to eight bytes per pair of lookups.
Testing with image_decode_bench show performance
improvement by 20-25% on Elm and Kevin Chromebooks except
for small images with a gradient, which show a slowdown.
However, the patch will introduce some memory hungry code
which lasts only while decoding a frame. The change in
memory requirement is from 4096 bytes to 4096*8 bytes.

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.

Wuffs ships as a "single file C library". Previously, that single file
was a .h file. Now it is a .c file.
The contents of the file are practically the same. The different file
name extension means that the build system (GN/ninja) will treat that
file as a .c file, or "something that generates code", and not merely a
.h file, or "something #include'd by things that generate code".
This should hopefully fix mysterious linker errors when updating the
third_party/wuffs checkout results in the builder doing no work, since
no .c files changed.
