[bigint] Support parsing of BigInt literals 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).

[ast] Move AstValue implementation into Literal 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.

Normalize casing of hexadecimal digits 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.
