a0690b69da math: add functions; update tests and special cases
Added special cases to comments for asin.go and fabs.go.
Added Trunc() to floor.go and floor_386.s.  Fixed formatting
error in hypot_386.s  Added new functions Acosh, Asinh,
Atanh, Copysign, Erf, Erfc, Expm1, and Log1p.  Added
386 FPU version of Fmod.  Added tests, benchmarks, and
precision to expected results in all_test.go.  Edited
makefile so it all compiles.

a3d1045fb7 1) Change default gofmt default settings for
parsing and printing to new syntax.

   Use -oldparser to parse the old syntax,
   use -oldprinter to print the old syntax.

2) Change default gofmt formatting settings
   to use tabs for indentation only and to use
   spaces for alignment. This will make the code
   alignment insensitive to an editor's tabwidth.

   Use -spaces=false to use tabs for alignment.

3) Manually changed src/exp/parser/parser_test.go
   so that it doesn't try to parse the parser's
   source files using the old syntax (they have
   new syntax now).

4) gofmt -w src misc test/bench

3rd set of files.

3b864e4195 convert low-level (used by testing) packages to
whole-package compilation.  new Makefiles,
tests now in separate package

	bytes
	flag
	fmt
	io
	math
	once
	os
	reflect
	strconv
	sync
	time
	utf8

delete import "xxx" in package xxx.

inside package xxx, xxx is not declared
anymore so s/xxx.//g

delete file and package level forward declarations.

note the new internal_test.go and sync
and strconv to provide public access to
internals during testing.  the installed version
of the package omits that file and thus does
not open the internals to all clients.
