Leszek Swirski 39e2d97bc4 [sfi] Replace start/end position with UncompiledData
Add new types for function data for SharedFunctionInfo, for uncompiled
functions. UncompiledData holds start/end positions, allowing us to
remove these fields from SFI. Uncompiled functions with pre-parsed
scope data now hold an UncompiledDataWithScope that has a pointer to
PreParsedScopeData -- this allows us to also remove the start/end pos
from PreParsedScopeData.
