Add benchmark args

[marvinborner]

I tried to normalize the benchmarks to around 1-1.5s. Many of the benchmarks are either constant folded, timeout immediately, or timeout with nontrivial arguments. Here are my notes, @phischu might want to investigate:

JS

folklore_to_fact/sudan_goto >1 OVERFLOW
nofib/integer TIMEOUT
folklore_to_fact/tak INF
folklore_to_fact/takl TIMEOUT
folklore_to_fact/tak_goto INF
folklore_to_fact/even_odd_goto 4096 OVERFLOW
folklore_to_fact/deriv INF
folklore_to_fact/cps_tak OVERFLOW
folklore_to_fact/sudan >1 TIMEOUT

LLVM

nofib/integer TIMEOUT
nofib/cryptarithm1 >1 TIMEOUT
tail_fib INF
tak INF
sudan_goto >1 TIMEOUT
takl TIMEOUT
merge SEGFAULTS >150K
perm 2 SEGFAULTS >2
ack_goto 7 TIMEOUT >7
tak_goto INF
deriv INF
cps_tak INF
sudan 1 TIMEOUT >1
ack 7 TIMEOUT >7

but otherwise this should be mergable, even if not all benchmarks are included right now.
