An optimization in li checks if a value has all their "n" LSBs set to
one, and their "64-n" MSBs set to zero. This is done by checking
base::bits::IsPowerOfTwo(value + 1), but this doesn't cover the case
when only MSB is zero, and other bits are one. Added another check that
covers the missing case, this also fixes Dsubu test.

For determining whether unaligned memory accessed is allowed, it is
actually sufficient to pass the MachineRepresentation instead of the
MachineType.
As the MachineRepresentation is an enum, this allows to store the set
of unsupported types as an EnumSet instead of std::vector.

Previously TryToName bailed out for Oddball keys (i.e. when passing true
or false as the key), which meant that for example the generic
KeyedLoadIC would always bail out to the %KeyedGetProperty runtime
function. But handling Oddball keys is fairly easy, since every oddball
value carries it's unique string representation. Adding just this case
to the CodeStubAssembler::TryToName method boosts this simple
micro-benchmark by a factor of 4x:
const n = 1e7;
const obj = {};
const key = true;
console.time('foo');
for (let i = 0; i < n; ++i) {
if (obj[key] === undefined) {
obj[key] = key;
}
}
console.timeEnd('foo');
It also shows on the ARES-6 ML benchmark and on several Speedometer
tests, where objects are being used as dictionaries and the developers
rely on the implicit ToString conversions on the property accesses.
In the ARES-6 ML benchmark, the number of calls to %KeyedGetProperty
is reduced by 137,758.

My goal was to move breakpoint API to native with minimal changes around, so on inspector side we use v8::debug::BreakpointId instead of String16, on v8::internal::Debug we use i::BreakPoint object instead of break point object created inside of debug.js.
There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs.
Drive by: debugger-script.js and usage of debugger context in inspector code base.

Per https://github.com/tc39/proposal-async-iteration/pull/102/files:
AsyncGeneratorResolve no longer unwraps a value component. Instead, the value is
unwrapped before the builtin call via Await, allowing Promise rejections to
affect the generator control flow.
Thus, all `yield <expr>` implicitly become `yield await <expr>`.
Additionally, `return <expr>` becomes `return await <expr>`. Finally, when the
generator is resumed with `.return()`, the parameter passed to .return() is
awaited before generator execution properly continues).
