Fixes#4904.
The problem was that when the test runs the heap had grown to ~100MB,
so GC allows it to grow to 200MB, and so the test fails.
Moving the test to a separate process makes it much more isolated and stable.

swig >= 2.0.9 requires the size of int values to be passed via a command line flag. Should swig complain about the -intgosize not being supported, then alert the user to their outdated version of swig.

Replacement for CL 7370053 which attempted to make fallthrough's
syntactically a part of switch statements. Because they may be
labeled, fixing that CL completely would require too much spec
surgery.

Fixes#4945.
Most examples in this issue now better, but #10 is incomplete and I'm not
certain how to reproduce it. It actually looks like a go/types problem, since
the type being reported is coming directly from that package.
Please reopen the issue if you disagree.

Bridge methods for embedded interfaces were
passing the interface twice: once as receiver,
once as first param.
Covered by $GOROOT/test/ddd.go.
Also:
- invent names ("arg%d") for parameters if missing.
- refactoring: move common code for bridge methods into
createParams and emitTailCall.

Now that untyped expressions are done in two phases, the
identity of operand.expr is used as a map key; when reusing
operand values we now must be careful to update the
expr field.

Completely rethought shift expression type checking.
Instead of attempting to type-check them eagerly, now
delay the checking of untyped constant lhs in non-
constant shifts until the final expression type
becomes clear. Once it is clear, update the respective
expression tree with the final (not untyped) type and
check respective shift lhs' where necessary.
This also cleans up another conundrum: How to report
the type of untyped constants as it changes from
untyped to typed. Now, Context.Expr is only called
for an expresion x once x has received its final
(not untyped) type (for constant initializers, the
final type may still be untyped).
With this CL all remaining std lib packages that
did not typecheck due to shift errors pass now.
TODO: There's a lot of residual stuff that needs
to be cleaned up but with this CL all tests pass
now.

The Name field of the stat structure is variable length
and the marshalling code in package syscall requires
a buf long enough to contain the Name as well as the
static data. This change makes sure that the buffer in
os.Rename is allocated with the appropriate length.

There are some function pointers declared by 6c in
package runtime without initialization and then also
declared in package runtime/cgo with initialization,
so that if runtime/cgo is linked in, the function pointers
are non-nil, and otherwise they are nil. We depend on
this property for implementing non-essential cgo hooks
in package runtime.
The declarations in package runtime are 6c-compiled
and end up in .6 files. The declarations in package runtime/cgo
are gcc-compiled and end up in .o files. Since 6l links the .6
and .o files together, this all works.
However, when we switch to "external linking" mode,
6l will not see the .o files, and it would be up to the host linker
to resolve the two into a single initialized symbol.
Not all host linkers will do this (in particular OS X gcc will not).
To fix this, move the cgo declarations into 6c-compiled code,
so that they end up in .6 files, so that 6l gets them no matter what.
