Since fp->symsz includes the size of the header
in the new symbol table format, we were reading
past the end and decoding a few garbage symbols
from data in the pc/line table.

- convert all formatters that require a *token.FileSet to
consistenly use a *PageInfo as first argument instead
- adjust templates correspondingly
- fix outstanding bug from previous CL 8005044
Going forward, with this change the affected functions have
access to the full page "context" (PageInfo), not just the
respective file set. This will permit better context-dependent
formatting in the future.

The gofmt function was returning a string, which isn't the right type.

A HMUL node appears in some constant divisions, but
to observe a false negative in race detector the divisor must be
suitably chosen to make sure the only memory access is
done for HMUL.

For Go 1.1, stop checking the rlimit, because it broke now
that mheap is allocated using SysAlloc. See issue 5049.

The arm gentraceback mishandled frame linkage values pointing
to the assembly return function. This function is special as
its frame size is zero and it contains only one instruction.
These conditions would preserve the frame pointer and result
in an off by one error when unwinding the caller.

The changes are almost completely self-contained
in the new file linkify.go. The other changes are
minimal and should not disturb the currently
working godoc, in anticipation of Go 1.1.
To disable the feature in case of problems, set
-links=false.

At some point in the past, I believe the GCD algorithm was setting d to
be negative. The RSA code has been correcting that ever since but, now,
it appears to have changed and the correction isn't needed.
Having d be too large is harmless, it's just a little odd and I
happened to notice.

This keeps the logic about how to set the thread-local variables
m and g in code compiled and linked by the gc toolchain,
an important property for upcoming cgo changes.
It's also just a nice cleanup: one less place to update when

The right operand of a && and || is only executed conditionnally,
so the instrumentation must be more careful. In particular
it should not turn nodes assumed to be cheap after walk into
expensive ones.

The ARM implementation of runtime.cgocallback_gofunc diverged
from the calling convention by leaving a word of garbage at
the top of the stack and storing the return PC above the
locals. This change stores the return PC at the top of the
stack and removes the save area above the locals.
Update #5124
This CL fixes first part of the ARM issues and added the unwind test.
