ae03a192e0 timing.log: significant improvements after custom algorithms

6fe82e6b96 test/bench: note changes after recent improvements to locking and runtime 
Some tests are significantly faster (50%), a few are slower (up to 30%).
Fannkuch is confusing: parallel code is a little slower for gc, non-parallel and all gccgo runs are faster.

5236814edd timing: update numbers for regex-dna 
After improved compilation of append, regexps improve and regex-dna is 35% faster.

e3634aad9d test/bench: update timings; moving to new machine. 
Interesting comparisons between old and new machine,
and relationship between gccgo and gc.

65ece70812 test/bench: update timings for new GC 
Some significant improvements; e.g. pidigits goes from 8.33 to 6.37

Also add gccgo for regex-dna.

85f5bb8216 test/bench: a couple fixes to timing.sh 
- Skip the gccgo tests if we don't have it
- Add -lm so nbody.c will compile
- Pass 2098 to the meteor test (cf. the shootout site)

7a5852b50e update timing logs for benchmarks. 
some significant improvements:
	reverse-complement
	nbody (gccgo only)
	regex-dna
	pidigits
one mysterious drop:
	binary-tree.go (gccgo only)

0263103a05 move evaluation of null-matching instructions one iteration earlier. 
performance hit of about 20% but more intuitive results for submatches.
we need a good regexp package at some point.

Fixes #110.

7f0dd8b1b7 new benchmark results. 
main changes:
	gccgo is much slower on  binary-tree and fannkuch
	6g seems to struggle with alignment of loops in nbody (dignosis uncertain)
	6g is a little faster at regexps and concurrency
