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.

LiftoffRegister is an abstraction over Register and DoubleRegister.
Many functions in Liftoff do not need to distinguish GP and FP
registers. LiftoffRegister allows to implement most functions
generically. Accessors allow to convert them back to Register or
DoubleRegister.
Both register types are represented in a unified index space, which
allows to extend this concept to more register types and implement
aliasing in a straight-forward manner.
Many functions currently only implement the GP case. FP will be added
later.

In the special case of KeyedLoadIC, where the key is always undefined,
LowerCheckEqualsInternalizedString fails and triggers deoptimization
loops. It's because {exp}, which is undefined_string, does not match
{val}, which is undefined_value.
This patch drops the convertion from undefined_value to undefined_string
for undefined key in KeyedLoadIC. It makes undefined key be able to pass
LowerCheckEqualsInternalizedString and avoids the deoptimization loops.
