Currently, Torque's builtin pointers store a Code target underneath and callsites generate a kArchCallCodeObject opcode. When embedded builtins are enabled, the call thus first calls the on-heap trampoline, which finally jumps to the target off-heap builtin code. This will no longer be possible in jitless mode, since on-heap code must not be executable. As a step towards changing the way builtin pointers are called (function pointers will hold the builtin index as a Smi, and callsites look up the off-heap target address and jump there), this CL adds a dedicated opcode for builtin pointer calls to the compiler pipeline. The calling mechanism itself is unchanged, changes there will happen in a follow-up. Drive-by: rename 'FunctionPointer' in torque/ to 'BuiltinPointer'.

In the process, add the bint type (which stands for Best-INTeger), which implements Torque's idea of CSA's ParameterMode. It maps to a different type on 32-bit (Smi) and 64-bit (intptr). There are convert operators that are either no-ops or conversions to-and-from Smi and intptrs on the each platform, depending on the underlying type for bint. This allows Torque code to git most of the benefits of ParameterMode without having to explicitly pass around the mode, since it is almost always OptimalMode anyways.

Enable --harmony-string-matchall by default. String.prototype.matchAll behaves similarly to String.prototype.match, but returns a full regexp result object for each match in a global or sticky regexp. This offers a simple way to iterate over matches when access to e.g. capture groups is needed. const string = 'a b c'; const regex = /[ac]/g; for (const match of string.matchAll(regex)) { console.log(`${match[0]} at ${match.index}`); } // a at 0 // c at 4 More information can be found here: https://github.com/tc39/proposal-string-matchall Drive-by: Update debug evaluate side effect expectations to handle String.p.matchAll and RegExp.p[@@matchAll] Bug: v8:6890 Change-Id: Ie3e712af66689936b7d2a15df705b792ccf06bd3 Reviewed-on: https://chromium-review.googlesource.com/c/1377774Reviewed-by:Mathias Bynens <mathias@chromium.org> Reviewed-by:
