d8416f5524 Intrinsics in the INLINE_FUNCTION_LIST are now avaliable without '_', too. 
This involved renaming apart a few more intrinsics. In the long run,
we want to clean up redundant intrinsics which just delegate.

f6cd009efd ES6: Make function name configurable 
Function name property is now standardized in ES6. It was a Mozilla proprietary
extension before. With ES6, the property was made configurable, so that it can
be used instead of another proprietary property, displayName.

This is a revert of revert c791d84112.

Last time this broke a Chrome browser test which has since been updated:

91b87e7a28 Do not create unresolved variables when parsing arrow functions lazily 
Arrow function parameter lists are parsed as expressions. When an identifier
is found a VariableProxy is created and added to the list of unresolved
variables for the scope. When parsing a function lazily, the scope has been
already resolved, so with this patch only the VariableProxy is created,
without adding it as an unresolved variable in the scope.

e5184734b3 Another attempt to fix regress-crbug-178790.

obviously doesn't give us that much stack, anyway.

54570cfa74 PPC aftermath: Fix regress-crbug-178790. 
The test fails on XP only, so let's tentatively raise the stack limit more. We probably need to investigate what a tighter limit might be and (more importantly) what the underlying reason for the failure is.

Hopefully 1800kB is enough, we can't test this via try jobs, because we don't have XP try bots. :-/
