Subject: Add new configure argument --optimize-for-size

Uses -Os for GCC/Clang/ICC, /O1 for MSVC.

Might be used in the future to control compile time features also
(eg using a large precomputed table, vs not). Does not have any
influence on module selection, just informs the build that a smaller
binary is preferable.
