eddf5edb62 Cleaned up BuildLoadNamed/BuildStoreNamed. 
This is a refactoring-only CL and the second one in a series for enabling
inlining of accessors. It makes BuildLoadNamed and BuildStoreNamed a bit more
uniform and makes it clear that they both handle monomorphic accesses only.

80c35c6522 Always set the callee's context when calling a function from optimized code. 
This is necessary even for recursive calls because we're sharing optimized code among closures, which could call each other and have distinct contexts.

0f800eef8e Cleaned up Hydrogen function signatures related to property access. 
This is a refactoring-only CL and the first one in a series for enabling
inlining of accessors. The naming and argument order has been unified a bit, and
some tests have been pushed to the caller in order to get a simpler
signature. Note that the latter temporarily introduces some code redundancy, but
this will be cleaned up in one of the next CLs.

abede994d9 Refactor incremental marking to use static visitor. 
This is a refactoring only change that switches incremental marking to
use a static object visitor. It also shares the common code between the
non-incremental and the incremental marker. Sharing that would require
semantical changes will be done later.

f99dda8dab Let DescriptorArray::Append insert at proper position, avoiding need for resorting. 
Using insertion-sort won't have too much of an overhead for the short arrays for bootstrapping (which are probably snapshot anyway).
CopyAppendCallbackDescriptors was extending and sorting the array in a loop. By using an append that inserts at the right position we do not need to resort in each iteration.

Additionally remove Sort and rename SortUnchecked to Sort. The IsSortedNoDuplicates check is moved into InitializeDescriptor.

71618ee6aa The deferred handes list belongs to the Isolate and not to the 
HandleScopeImplementer (since it isn't something specific to a
particular thread executing on an Isolate). This patch ensures correct
traversal of the handles when when multiple compilations are queued
up.

Callsites now have to manually lookup transitions if required. This
avoids unnecessary overhead of looking up transitions when we don't need
them. This also allows us to use IsFound() in many places where
IsProperty() was required previously.

Note that changes on the prototype chain should already be handled by
StubCompiler::CheckPrototypes, if not, it is a bug there and not in
LookupForWrite. Furthermore, neither test262 nor WebKit layout tests hint at a
compability issue, so it should be safe to remove a redundant check.
