Fixes#3495.
I adapted fmt.TestCountMallocs to fix the
existing tests. As the resulting tests did not
appear to belong to either itoa or ftoa I moved
them into their own file.

My theory is that the call to f() allocates, which triggers
a garbage collection, which itself may do some allocation,
which is being counted. Running a garbage collection
before starting the test should avoid this problem.
Fixes#2894 (I hope).

Unexports runtime.MemStats and rename MemStatsType to MemStats.
The new accessor requires passing a pointer to a user-allocated
MemStats structure.
Fixes#2572.

(Note that the Int and Uint benchmarks use different test sets
and thus cannot be compared against each other. Int and Uint
conversions are approximately the same speed).

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
4th set of files.

note the new internal_test.go and sync

internals during testing. the installed version
of the package omits that file and thus does
not open the internals to all clients.
