Reviewers: fschneider,
Message:
The original patch is in patch set 1 and 2 and patch set 3 is the changes to
record the position. Patch set 4 is just a rebase.
Description:
Increase coverage of global loads in optimized code
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.
