compiler: report correct errors for sink methods

    If somebody writes

    func (s []int) _() {}

    we should report an error.  Before this patch we were silently
    accepting this code, because we didn't report any errors about the
    receiver if the method was a sink.

    This patch is unfortunately slightly complex to handle the case of

    func (x int) _() {}

    which we can only detect after define_global_names.

    This fixes blank1.go in the current gc testsuite.

Limit perf data buffer during profiling

With high -j parallelism the autofdo tests can randomly fail.
autofdo uses Linux perf to record profiling data.
Linux perf uses a locked perf buffer. By default it has
around 516k buffer per uid (/proc/sys/kernel/perf_event_mlock_kb).

An individual perf record tries to grab the full 516k,
which makes parallel perf record fail.

This patch limits the perf buffer for individual perf record to 8k.
With the default settings this allows a parallelism of the test
cases of 16, which is hopefully good enough

(if not would need to add some kind of semaphore, or ask
the user to increase the limit as root)

I also removed an unneeded -o perf.data option

Thanks to Marcin to finally spotting the problem.

Passes bootstrap and test on x86_64-linux. Ok for trunk?

mksigtab.sh: recurse once when adding signals to SIGLIST

    On MIPS, SIGABRT is defined like this:
     #define SIGIOT   6
     #define SIGABRT  SIGIOT

    This breaks addsig which tries to append __SIGIOT_ to SIGLIST. Signal
    number 6 is later added to the output and go complains about a
    duplicate signal number.

    Fix by recursing once when obtaining the signal number from
    gen-sysinfo.go if the signal is defined as an alias of another signal.
    Also modify the sed expression to 's/.* = //' which is equivalent to
    the original expression but is less misleading given that it might not
    match a number.
