While we're at it, let's remove some "using" statements that also cause trouble.

Revert of Remove obsolete V8_INFINITY macro. (patchset #3 id:40001 of https://codereview.chromium.org/798413003/) Reason for revert: Speculative revert. This seems to block the current roll: https://codereview.chromium.org/819653003/ I retried several times, also with a new roll. The error is internal - but that doesn't make much of a difference.

Introduce a RandonNumberGenerator class. Refactor the random/private_random uses in Isolate/Context. The RandomNumberGenerator is a pseudorandom number generator with 48-bit state. It is properly seeded using either (1) the --random-seed if specified, or (2) the entropy_source function if configured, or (3) /dev/urandom if available, or (4) falls back to Time and TimeTicks based seeding. Each Isolate now contains a RandomNumberGenerator, which replaces the previous private_random_seed. Every native context still has its own random_seed. But this random seed is now properly initialized during bootstrapping, instead of on-demand initialization. This will allow us to cleanup and speedup the HRandom implementation quite a lot (this is delayed for a followup CL)! Also stop messing with the system rand()/random(), which should not be done from a library anyway! We probably re-seeded the libc rand()/random() after the application (i.e. Chrome) already seeded it (with better entropy than what we used). Another followup CL will replace the use of the per-isolate random number generator for the address randomization and thereby get rid of the Isolate::UncheckedCurrent() usage in the platform code.

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.
