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 eliminates the AstValue class, effectively moving its
implementation into the Literal AstNode. This should cause
no difference in behavior, but it does signal some shifts
in the underlying system. Biggest changes include:
- Reduction in AST memory usage
- No duplicate HeapNumbers in Ignition constant pools
- Non-String values are allocated either at constant pool
creation time (or at boilerplate creation time for literals),
rather than at AstValueFactory::Internalize() time.
There are a variety of test-only/debug-only changes due to these
switches as well.

Reuses the existing logic for BigInt.parseInt, adapted slightly
to allow octal and binary radix prefixes (and to support parsing
of a raw character buffer, rather than a v8::internal::String).
