This patch adds:
- VariableMode::kPrivateMethod
- VariableMode::kPrivateSetterOnly
- VariableMode::kPrivateGetterOnly
- VariableMode::kPrivateGetterAndSetter
And replace the previous RequiresBrandCheckFlag by inferring
whether the brand check is required from these VariableModes.
It is then possible to check duplicate non-complementary
accessors in the parsers and throw early errors, and allow
complementary accessors to be associated with the same
private name variable.
This patch also adds the following AssignType:
- PRIVATE_METHOD
- PRIVATE_GETTER_ONLY
- PRIVATE_SETTER_ONLY
- PRIVATE_GETTER_AND_SETTER
corresponding to the new VariableModes so that it's possible
to generate specialized code for different type of
private accessor declarations.

Locally tested, octane results are the same or better when using
branchful decompression in generated code.
The biggest one is DeltaBlue in x64 which improves about 25%.
x64's EarleyBoyer is another important one with ~10% improvement.

This patch adds a new assign type `PRIVATE_METHOD`. We now use this
for private method references in the form `obj.#key` when `#key`
resolves to a private method.
To obtain the type of the key variables after scope analysis, this
patch add a bit to Variable to recognize private method variables
whose load requires a brand check.
Also renamed `PropertyExpressionWithPrivateFieldKey` in ExpressionType
to `PrivateReference` and added `PRIVATE_CALL` to `CallType` - we'll
use the new types later when we implement private methods, which
require special brand checking semantics to load methods directly
from the context instead of from the object in order to save memory.

... in favor of Isolate*. It seems that it's better to be uniform in
using Isolate* or isolate root value, so if we decide to pass isolate
root value instead of Isolate* it should better be done everywhere and
it will be a separate CL anyway.
Regarding the "optionality" of the isolate parameter - C++ compilers
are smart enough to optimize it away during inlining.

This replaces all typedefs that define types and not functions by the
equivalent "using" declaration.
This was done mostly automatically using this command:
ag -l '\btypedef\b' src test | xargs -L1 \
perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg'
Patchset 2 then adds some manual changes for typedefs for pointer types,
where the regular expression did not match.
