Remove SmallExp and -DSMALL_EXP?

[Artoria2e5]

I was a little confused by the ini referring to a kernel that does not seem to be used anywhere. So I wondered whether SMALL_EXP still does anything at all, and:

$ grep -r SMALL_EXP src
src/mfakto.cpp:      strcat(program_options, " -DSMALL_EXP");
src/mfakto.ini:# depending on other settings: -g / -O3, -DCHECKS_MODBASECASE, -DCL_GPU_SIEVE, -DSMALL_EXP
src/perftest.cpp:    strcat(program_options, " -DSMALL_EXP");

It does not appear in any OpenCL code, only lingering around in the C++ bits for building clBuildProgram options. Maybe it's time to retire that config entry?

Oliver, the original developer, had plans to add support for small exponents:

mfakto/todo.txt

Line 151 in 7c9f20b

merge mfaktc changes: small exps: should correct failing test

However, he quit before this ever happened. Would people find support for small exponents to be useful?

Hummmmmmmmm. I am having trouble finding where such a change is in mfaktc. I mean, I'm all for parity where it makes sense...
