re PR go/61880 (Linking with external functions in C does not work in GO when using gccgo, while it works in gc)

	PR go/61880
compiler: symbol names should have '.' replaced with '_'

Package and symbol names issued by the cgo tool and compiler
should be the same for the object files to link.

A minimal change to fix only:

The Go frontend passes closures through to functions using the
functions __go_set_closure and __go_get_closure.  The
expectation is that there are no function calls between
set_closure and get_closure.  However, it turns out that there
can be function calls if some of the function arguments
require type conversion to an interface type.  Converting to
an interface type can allocate memory, and that can in turn
trigger a garbage collection, and that can in turn call pool
cleanup functions that may call __go_set_closure.  So the
called function can see the wrong closure value, which is bad.

This patch fixes the problem in two different ways.  First, we
move all type conversions in function arguments into temporary
variables so that they can not appear before the call to
__go_set_closure.  (This required shifting the flatten phase
after the simplify_thunk phase, since the latter expects to
work with unconverted argument types.)  Second, we fix the
memory allocation function to preserve the closure value
across any possible garbage collection.

A test case is the libgo database/sql check run with the
environment variable GOGC set to 1.

	PR go/61308

compiler: Handle enclosing vars for function type in function lit.

This fixes a dumb bug in which the enclosing vars were
incorrectly cleared when a function literal contains a
reference to a function type.  The test for this will go into
the master repository in the change at
http://codereview.appspot.com/121200043 .

From-SVN: r213618

	PR go/61308
	PR go/61866

compiler: Don't cast index expr to int before bounds check.

This fixes http://gcc.gnu.org/PR61866 : on a 32-bit system,
casting an int64 index to int drops the upper 32 bits of the
value, and thus can cause an out-of-range index to appear to
be in range.

This undoes part of change 1318:fa6e0c716dba
(https://codereview.appspot.com/104610044) and therefore
breaks http://gcc.gnu.org/PR61308 again.  I have a separate
patch for that (http://codereview.appspot.com/122020043).  In
addition to undoing part of that change, this patch adds code
to avoid a compiler crash.  This changes PR61308 from a
compiler crash to an incorrect error message.

pointing to a zero value for that type.  This is implemented
as a common variable.

	* go-gcc.cc (Gcc_backend::implicit_variable): Add is_common and
	alignment parameters.  Permit init parameter to be NULL.

If the same type was embedded in a struct at different levels,
only the first embedded instance was considered when building
the set of all methods.  A second instance was ignored, even
if it was at a higher level and should therefore override the
first instance.

Test case is bug485.go in master repository.
