5f5dcfbc15 - gofmt these files 
- remove use of implicit string concatenation
- these appear to be the only files correctly compiling under test
  that used implicit string concatenation

864c6bcbc7 test/bench: use range in reverse-complement 
1.9s	gcc reverse-complement.c

reverse-complement.go
4.5s / 3.5s	original, with/without bounds checks
3.5s / 3.3s	bounds check reduction
3.3s / 2.8s	smarter garbage collector
2.6s / 2.3s	assembler bytes.IndexByte
2.5s / 2.1s	even smarter garbage collector
2.3s / 2.1s	fix optimizer unnecessary spill bug
2.0s / 1.9s	change loop to range (this CL)

b0683bd77a move ReadFile, WriteFile, and ReadDir into a separate io/ioutil package.

6fc820729e go: makes it build for the case $GOROOT has whitespaces 
the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.

this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.

Fixes #115.

688ffc1dc1 test/bench revisions; 
* reverse-complement: port C algorithm to Go
	saves 30% on my MacBook Pro and makes it a fairer comparison.
  * test reverse-complement with and without GC (another 15%)
  * revise timing.sh to work on more systems
  * avoid two glibcisms in fasta.c

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.

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
