Author: jkummerow <jkummerow@chromium.org>

Reduce binary size of Builtins::CallableFor

by pulling parameterizable things out of the case-blocks.
No change in functionality.

BUG= chromium:714894 

Review-Url: https://codereview.chromium.org/2854273004
Cr-Commit-Position: refs/heads/master@{#45066}

[modify] https://crrev.com/133ef93afa74f1d08919c89b358b8e0da5323cdb/src/builtins/builtins.cc
[modify] https://crrev.com/133ef93afa74f1d08919c89b358b8e0da5323cdb/src/interface-descriptors.h

Should be fixed by #7; in fact Builtins::CallableFor should be smaller than before the size increase now.
