runtime: partial stack trace should print that it's partial

[griesemer]

When getting a stack overflow, say due to an endless recursion, the stack trace may only
contain the top-most n stack frames, and eventually abruptly ends in something like:

code.google.com/p/go.tools/go/types.WriteType(0x210de8bd0, 0x0, 0x221065d9f0,
0x210ea3bd0)
    /Users/gri/golib/src/code.google.com/p/go.tools/go/types/typestring.go:95 +0x803 fp=0x2251d142d0
code.google.com/p/go.tools/go/types.WriteType(0x210de8bd0, 0x0, 0x221065d900,
0x2112a7dc0)
    /Users/gri/golib/src/code.google.com/p/go.tools/go/types/typestring.go:104 +0x670 fp=0x2251d14468
created by testing.RunTests
    /Users/gri/go/src/pkg/testing/testing.go:471 +0x978

goroutine 16 [chan receive]:
testing.RunTests(0x2f1680, 0x596ce0, 0x1a, 0x1a, 0x0)
    /Users/gri/go/src/pkg/testing/testing.go:472 +0x9a8
testing.Main(0x2f1680, 0x596ce0, 0x1a, 0x1a, 0x59ba80, ...)
    /Users/gri/go/src/pkg/testing/testing.go:403 +0x8c

exit status 2

If the stack frame on top of the one indicated via "created by
testing.RunTests" is not the first one invoked, there should be some indication of
that. For instance with ... as in:


code.google.com/p/go.tools/go/types.WriteType(0x210de8bd0, 0x0, 0x221065d9f0,
0x210ea3bd0)
