This reverts commit c166945083, as well as
followup change "Do not look for existing shared function info when compiling a new script."
(commit 7c43967bb7).

Each Script object now keeps a WeakFixedArray of SharedFunctionInfo
objects created from this script.
This way, when compiling a function, we do not create duplicate shared
function info objects when recompiling with either compiler.
This fixes a class of issues in the debugger, where we set break points
on one shared function info, but functions from duplicate shared function
infos are not affected.
