This CL modifies the ast-numbering phase to collect function literals which
should be compiled eagerly. This is then used to eagerly compile the inner
functions before compiling the outer function. This will be used to queue
compilation jobs on the CompilerDispatcher in a later CL.
This CL moves the compilation of eager inner functions out of the
GetSharedFunctionInfo function and instead compiles them explicitly. This
simplifies GetSharedFunctionInfo and also means there is no need to pass a
LazyCompilationMode to the function, so this concept has been removed.

Exchanged the ZoneList for a ZoneChunkList to avoid
unnecessary growing.

Since ZoneLists are essentially non-standard ZoneVectors and have a bad
growing behaviour (ZoneList-allocations make up ~50% of website parse
zone memory) we should stop using them. The zone-containers are merely
a clean-up, with none of them actually better suited to be used with
zones. This new datastructure allows most operations of a LinkedList (
except pop_first and insertAt/removeAt) but uses about the same memory
as a well-initialized ZoneVector/ZoneList (<3% overhead with reasonably
large lists). It also never attempts to free memory again (which would
not work in zones anyway).
The ZoneChunkList is essentially a doubly-linked-list of arrays of
variable size.
Some test-results where I tried storing 16k pointers in different list
types (lists themselves also zone-allocated):
List type Zone memory used Time taken
-----------------------------------------------------------------------
Zone array (for comparison) 131072 B
Ideally initialized ZoneList 131088 B 0.062ms
ChunkZoneList 134744 B 0.052ms <--new thing
ZoneDeque 141744 B
ZoneLinkedList 393264 B
Initially empty ZoneList 524168 B 0.171ms <--right now
ChunkZoneList only push_front 524320 B
