Previously, we would output \x5c to escape a backslash, but this is
invalid JSON and it would crash Turbolizer. Use \u005c instead.

This will be used for disassembling individual wasm function for
showing them in devtools.
The PrintAst function now also optionally provides an offset table
mapping from byte offset to line and column in the generated text.

We divide character ranges into
- BMP, matched normally.
- non-BMP, matched as alternatives of surrogate pair ranges.
- lone surrogates, matched with lookaround assertion that its indeed lone.

VS 2015 supplies a conforming snprintf implementation, so #define
snprintf is no longer needed. Also, VS 2015 checks for #define of
snprintf and treats it as a fatal error.

Use simple HAS-A relationship instead of obscure multiple inheritance.
In theory, UBSan should be totally happy with this, but it still isn't.
This seems to be a bug in UBSan, see e.g.

This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

Our clang/win build currently uses MSVS's C library, so it doesn't have
snprintf but it does have sprintf_s.
