`mvn xd, xn` is an architectural alias for `orn xd, xzr, xm`, so this
doesn't change code generation at all, but it's tidier and it addresses
a TODO.

Alas, this involved quite a bit of copy-n-paste between the
architectures, but this is caused by the very convoluted
relationships, lifetimes and distribution of responsibilities. This
should really be cleaned up by moving code around and using STL maps,
but that's not really a priority right now.

Bonus: Fixed leaks in the ARM64 disassembler tests.

This patch adds the two TypedArray methods indexOf and lastIndexOf,
which are similar to the methods on Arrays. Tests are ported from
arrays as well.

Patch from Daniel Ehrenberg <dehrenberg@chromium.org>.

Cr-Commit-Position: refs/heads/master@{#28495}

The sort method of TypedArrays sorts in numerical order by default.
This patch implements sorting based on Arrays and adds a test.
The length of %TypedArray%.prototype.sort, like Array.prototype.sort,
seems to be unspecified in ES6, so this patch lets it have the value
1, to match our interpretation for Array.prototype.sort (though 0
would also be a sensible length).

This patch adds the reverse method to TypedArrays, together with a
test. The test also runs for normal Arrays, since I didn't see a

A future version of GN will validate that any files taken as inputs to a step
were generated by public dependencies of that target. Some targets in Chrome
depend on the results of the snapshot.
