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.

The riscv64 Hifive Unmatched is the only platform that
failed on testcase TestAnalyzeAnnotations occasionally
after CL 332954 had merged. The failure happens when
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.

The "someTimeout" constant in the net test is “just to test that
net.Conn implementations don't explode when their SetFooDeadline
methods are called”. It was set to 10 seconds, which is short enough
that it could actually matter on some platforms.
Since the point of the constant is just to make sure methods don't
explode, we should set it to be at least a couple of orders of
magnitude longer than the test: then it is guaranteed not to have any
unintended side-effects.

The parser cannot distinguish a type parameter list of the form
[P *T ] or
[P (T)]
where T is not a type literal from an array length specification
P*T (product) or P(T) (constant-valued function call) and thus
interprets these forms as the start of array types.
This ambiguity must be resolved explicitly by placing *T inside
an interface, adding a trailing comma, or by leaving parentheses
away where possible.
This CL adjusts the parser such that these forms are
interpreted as (the beginning) of type parameter lists
if the token after P*T or P(T) is a comma, or if T is
a type literal.
This CL also adjusts the printer to print a comma if
necessary to avoid this ambiguity, and adds additional
printer tests.
