6459dabdae [turbofan] Second round of optimisation for unordered comparisons on arm/arm64.
Avoid explicitly branching to the false label on unordered when the condition
on the true branch will not catch the unordered case and let the code fall
through.

68870ab6ee move v8_use_external_startup_data to standalone.gypi
This allows the setting to be overridable by embedders,
at the cost of forcing embedders that don't build v8
using standalone.gypi to add this setting to their build
config.

b7caca9f9a When reading the map from a live object, use a barrier load
It could happen that we shrink a live object on the main thread (e.g.
MigrateFastToSlow) while we're sweeping the same page. The main
thread first creates a filler object that the release-stores the new
map. Therefore it's important to barrier load the map word of live
objects from the sweeper thread.

49baecc42b [turbofan] Mark arm64 cbz/cbnz tbz/tbnz instructions as branch instructions.
The instruction selector now selects pseudo instructions: CompareAndBranch or
TestAndBranch which are associated with their continuations so that generic
code in the code generator will treat them as branch instruction and will be
able to apply optimization like avoiding branches when the code can falltrhough.

4fa7ae1c07 Optimize Object.seal and Object.preventExtensions
They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.

This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).
