The arbitrary sleep in this test is empirically not always long enough
on slower builders. However, we know the exact number of connections
that should be dialed: we can wait on that number in the dial hook
instead.

This change skips the test if that particular failure mode is
encountered on those platforms; the skip can be removed if and when

In the dict info, we need to save the SelectorExpr of a generic method
call when making its sub-dictionary entry. The generic method call will
eventually be transformed into a function call on the method shape
instantiation, so we may not always have the selector info available
when we need it to create a dictionary. We use this SelectorExpr as
needed if the relevant call node has already been transformed.
Similarly, we save the InstExpr of generic function calls, since the
InstExpr will be dropped when the function call is transformed to a call
to a shape instantiation. We use this InstExpr if the relevant function
call has already been transformed.
Added an extra generic function Some2 and a call to it from Some that
exercises the generic function case. The existing test already tests the
method call case.

Since we use existing instantiations from the symbol table when possible
(to make sure each instantiation is unique), we need to pop
instantiations of local types when leaving the containing scope.
g.stmts() now pushes and pops scope, and we do a Pushdcl() in g.typ0()
when creating an instantiation of a local type.
Non-instantiated local types (generic or not) are translated directly
from types2, so they don't need to be pushed/popped. We don't export
function bodies with local types, so there is no issue during import.
We still don't support local types in generic functions/methods.

The current -asan option does not print where the error occurred. The
reason is that the current implementation calls incorrect asan runtime
functions, which do not pass sp and pc where asan runtime functions are
called, and report the stack trace from the native code. But asan runtime
functions are called from cgo on a separated stack, so it cannot dump the
Go stack trace correctly.
The correct asan runtime function we should call is __asan_report_error,
which will pass sp and pc, and report where the error occurred correctly.
This patch fixes this issue.
Add the test cases.

ticks per second (freq) is over 1e12 which causing the timestamps
of two events are same.
There are 2 reasons causing big frequency:
1. RDCYCLE is HART based according to the riscv manual which makes
negative ticks delta
2. negative float64 -> uint64 is undefined and "lucky" negative float
is too big to handle for trace

In c-archive mode, when we turn off profiling, we restore the
previous handler for SIGPROF, and ignore SIGPROF signals if no
handler was installed. So if a pending signal lands after we
remove the Go signal handler, it will not kill the program.
In the current code there is a small window, where we can still
receive signals but we are set to not handling the signal. If a
signal lands in this window (possibly on another thread), it will
see that we are not handling this signal and no previous handler
installed, and kill the program. To avoid this race, we set the
previous handler to SIG_IGN (ignoring the signal) when turning on
profiling. So when turning off profiling we'll ignore the signal
even if a stray signal lands in the small window.
