Fix a TODO from Ben to change the macro argument order to match the
actual order in wasm code.
After this fix, we can remove the individual {WASM_CALL_INDIRECT[0-5]}
macros and implement them via a common variadic macro.
Also, rename {WASM_CALL_INDIRECT_TABLE0} to {WASM_CALL_INDIRECT_TABLE}.
The name was confusing, because this macro explictly allows to set a
table index different from 0. Thus, just drop the "0" in the name.
The individual test changes were done via a vim macro, to avoid manual
errors.

This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.
Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.
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.

This CL modifies the following to be LEB128:
* Function table indices
* Import table signature indices
* Export table function indices
* Function signature param count
* br/br_if break depth
* br_table target count
* block/loop expression count
Still to do:
* Import/export names (LEB128 count + inline data)
* Data segments (LEB128 offset + size + inline data)
* Function header stuff (should seperate into function sig and body sections)
* Memory access alignment + offset (still discussing)

As discussed in person, this adds the code from v8-native-prototype into
V8 proper, guarded by GYP flags that do not build the code by default.
Passing wasm=on to 'make' or setting v8_wasm as a GYP flag activates
building of this code.
An additional header file is added to and exported from the compiler
directory, src/compiler/wasm-compiler.h. This exposes a limited interface
with opaque Node and Graph types to the decoder to build TF graphs, as
well as functions to compile WASM graphs.
The mjsunit tests added are blacklisted because they fail without the
WASM object exposed to JS, which is also disabled by the build config
option.
This corresponds closely to 5981e06ebc, with some formatting fixes and moving some files into src/compiler.
