Fix lvalue/rvalue context mixup Set_and_use_temporary_expression's
do_get_backend() method. Enhance Mark_lvalue_varexprs to handle
conversions and temporary reference expressions, since occasionally
the front end emits code such as "deref(conv(tempref)) = ...".
If there is a large stack frame the rs6000 -fstack-limit code would
calculate the new stack pointer value using two insns (an addis and
an addi), with r0 as temporary. Such instructions do not exist.
This patch changes add<mode>3 to expand using a different strategy in
such cases; to FAIL if there is no way to do it (namely, if the source
is r0 and there is no way to get a temporary reg); and it changes
rs6000_emit_allocate_stack to assert gen_add3_insn did in fact emit
instructions.

compiler: lvalue context fixes in Unary_expression::do_get_backend
A couple of the Backend::var_expression invocations in
Unary_expression::do_get_backend were selecting "lvalue" context
incorrectly (these var exprs were not in an assignment or LHS
position); fix is to change back to "rvalue" context.
compiler: fix undefined symbol error with unexported method
When an interface I1 in an imported package has an unexported method,
and is then embedded into another interface I2, in a different
package, that has other methods, and a type T2 is converted to I2, we
failed to ever define the required interface method table. Naturally
T2 must implement the unexported method, and must therefore either be
defined in the same package as I1, or embed a type from that package.
In this case the compiler was assuming that that package would define
the interface method table, but of course, since I2 was not defined in
that package, that did not happen.
The fix is to only assume that the interface method table will be
defined elsewhere in the case where T2 and I2 are defined in the same
package. The compiler ensures that all such interface method tables
are created, in Gogo::build_interface_method_tables. This requires
knowing the package in which an interface type is defined, a simple
tweak to the importer.
Testing this revealed that the special case for stub methods created
for the embedded unexported methods of T2 needs to be done for
function declarations as it currently is for function definitions, so
that the newly created interface method tables use the correct name.
Testing that revealed that the code to determine the pkgpath symbol
for such stub methods was wrong. It assumed that one could call
pkgpath_for_symbol on the pkgpath to get the pkgpath symbol. Would
that it twere so simple. Instead, add a function to look up the
package, which must be known, and fetch the pkgpath symbol.
