This operation was used to implement asm.js stores, but is obsolete
with asm.js stores now being lowered to normal graph nodes.

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.

* Avoid "using namespace" statements, which trigger clang's -Wheader-hygiene
warnings in jumbo builds.
* Undefine created macros at the end of source files.

Original issue's description:
> [turbofan] Take the immediate size in account when narrowing ia32/x64 word comparison operators.
>
> Trying to re-land http://crrev.com/1948453002 after fixing assembler-x64.cc in http://crrev.com/1962563003.
>
> Before this patch, we would emit a cmp or test with a memory operand only if both of the operands in the IR were loads. Now if either of them is a load and the other one is an immediate, we can use a memory operand if the load representation machine size is wide enough to represent the latter.
