In the cases where a global property cell cannot be used in the optimized code
use standard load ic to get the property instead of bailing out.

This is re-committing r7212 and r7215 which where reverted in r7239 with the addition of recoring the source position in the hydrogen code for the LoadGlobalCell instruction. To record that position an optional position field has been added to the variable proxy AST node.

Fix %_IsConstructCall handling in hydrogen: when called from inlined function return false constant directly instead of emiting HIsConstructCall.

Unoptimized code should already keep a reference to the SharedFunctionInfo,
let's use it instead of allocating a new object and prohibiting SharedFunctionInfo

The test suite builds the preparser test program and runs it on each .js file in
the test/preparser directory.
Currently it only checks that preparsing runs without crashing or erroring.
This also implicitly tests that the preparser library can be built.
