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.

9d7e39340d syscall: delay load of dll functions until they are called 
Before this change, syscall package would load
all dlls used anywhere in the go tree on startup.
For example, this program:

package main

import "fmt"

func main() {
       fmt.Printf("Hello world\n")
}

would load these dlls

kernel32.dll
advapi32.dll
shell32.dll
wsock32.dll
ws2_32.dll
dnsapi.dll
iphlpapi.dll

Most of these dlls are network related and are not used
in this program. Now the same program loads only

kernel32.dll
shell32.dll

This decreases start times somewhat.

This also relaxes the rules of which dlls can be included
in the standard library. We could now include system calls
that are not available on all versions of Windows, because
we could decide if we should call them during runtime.

4e5086b993 runtime: improve Linux mutex 
The implementation is hybrid active/passive spin/blocking mutex.
The design minimizes amount of context switches and futex calls.
The idea is that all critical sections in runtime are intentially
small, so pure blocking mutex behaves badly causing
a lot of context switches, thread parking/unparking and kernel calls.
Note that some synthetic benchmarks become somewhat slower,
that's due to increased contention on other data structures,
it should not affect programs that do any real work.

1b4dff0f69 exp/template: simplify the helper functions 
- create a pair of "Must" functions, one for templates, one for sets
- regularize the return values of the parsers so they can be wrapped by Must
- delete all the old Must functions and methods.
