Even though both are allowed in the style guide, it recommends to use
'using', as its syntax is more consistent with the rest of C++.
This CL turns all typedefs in wasm code to 'using' declarations.

This CL changes the usage pattern from

to
FOR_XXX_VALUES(i) { Use(i); }
which is way more intuitive.
Note that the replacement in the uses was done via regular expression,
so it's purely mechanical. In two locations I removed unneeded braces
around the macro, because they confused clang-format.
I plan to do more cleanups (remove redundant assignments within the
FOR_XXX_VALUES body) in a follow-up CL.

Linkage-related methods were declared in wasm-compiler.h and
implemented in wasm-linkage.cc. This required all users of e.g. wasm
call descriptors to include the whole wasm compiler header. Also, some
wasm linkage information is independent of turbofan and also used
outside of the compiler directory.
This CL splits off wasm-linkage.h (with minimal includes) and puts it
in src/wasm. This allows to use that information without including
compiler headers (will clean up several uses in follow-up CLs).

Previously, the V8 code base used an inconsistent mixture of uppercase

Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters
Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

Most prototype implementations are not fully supported in the
interpreter. This is the case at least for exception handling, simd, and
atomics. Any function can be redirected to the interpreter though,
either by passing --wasm-interpret-all, or by dynamically redirecting to
the interpreter for debugging.
Making the flags experimental keeps the fuzzer from playing around with
these flags.
Drive-by: Refactor tests which explicitly set the prototype flag to use
a new scope for that.

Currently SIMD integer comparison ops are implemented using Lt/Le, this is
sub-optimal on Intel, because all compares are done using pcmpgt(d/w/b) that
clobber the destination register, and will need additional instructions to
when using Lt/Le as the base implementation. This CL proposes moving to Gt/Ge
as the underlying implementation as this will only require swapping operands
on MIPS and is consistent with x86/ARM instructions.

I32x4UConvertI16x8Low, I32x4UConvertI16x8High, which unpack half of
an I16x8 register into a whole I32x4 register, with signed or unsigned
extension. Having separate Low/High opcodes works around the difficulty
of having multiple output registers, which would be necessary if we unpacked
the entire I16x8 register.

I16x8UConvertI8x16Low, I16x8UConvertI8x16High, similarly to above.

I8x16SConvert16x8, I8x16UConvertI16x8, which pack two source registers
into a single destination register with signed or unsigned saturation. These
could have been separated into half operations, but this is simpler to
implement with SSE, AVX, and is acceptable on ARM. It also avoids adding
operations that only modify half of their destination register.
