This optimization was disabled because 32-bit builds didn't properly find certain integer keys in maps anymore. The reason was that the runtime wasn't using ComputeIntegerHash for the full Signed32 range, but only for the SignedSmall range. This change improves the ARES-6 Basic test by around 6-7% on the steady state.

- Make it possible to store quarter-bytes instead of full bytes. - Don't store is_used; it can be recovered correctly based on the actual full parse (when a lazy function is eventually called) and has_forced_scope_allocation. - With the is_used change, the old testing approach (which compared a scope for which we didn't do scope allocation to the baseline) no longer made sense. Replaced it with a new testing approach, which is also closer to the actual usage. - First version (reverted): https://chromium-review.googlesource.com/725422 BUG=v8:5516 Change-Id: I1468af6670b689a104bd867377caa1d236070820 Reviewed-on: https://chromium-review.googlesource.com/733123Reviewed-by:

Clemens Hammacher authored
Before, the standard way to create a RegList was either: RegList list = (1 << 0) | (1 << 1) | ... or RegList list = rax.bit() | rdx.bit() | ... The first way allows to make the RegList constexpr, but needs comments to document which registers you are referring to, and it has no checks that all bits you set on the RegList actually belong to valid registers. The second one uses the symbolic names, hence is much more readable and makes it harder to construct invalid RegLists. It's not constexpr though, since the {bit()} method on the register types is not constexpr. This CL adds a constexpr accessor to get the code and bit of a constexpr Register, and adds a helper method to create a constexpr RegList like this: constexpr RegList list = Register::ListOf<rax, rdx, rdi>(); This new method is used in a number of places to test its applicability. Other uses of the old pattern remain and can be cleaned up later.

This removes all but one caller of Literal::raw_value(), thus hiding AstValue from the rest of the codebase. This is in preparation to move much of AstValue's implementation up into Literal itself, thus avoiding the overhead of the underling ZoneObjects and allowing us to remove complexity such as the cache of Smi-valued AstValues.
