Revert of Debugger: clear shared function info list when recompiling for liveedit.

Revert of Debugger: clear shared function info list when recompiling for liveedit. (patchset #1 id:1 of https://codereview.chromium.org/1270313003/ )

Reason for revert:
Sorry for revert, but this change breaks one of the webkit-unit-tests.

Example here: https://storage.googleapis.com/chromium-layout-test-archives/V8-Blink_Win/1178/layout-test-results/inspector/sources/debugger/live-edit-no-reveal-diff.txt

Not sure if the old expectations were right, or the new ones are. :)
