[aarch64-port-dev ] Another hotspot test failure

[Andy Johnson]

Test hotspot/test/compiler/8007722/Test8007722.java fails on aarch64 with
the following error:
Internal Error
(/home/andyj/openjdk-8/jdk8/hotspot/src/share/vm/c1/c1_LIR.hpp:93)
 assert(type() == t1 || type() == t2) failed: type check

The type() is 11 (long), t1 is 10 (int) and t2 is 15 (address).  I can only
find one instance of a call to LIR_Const::type_check(BasicType, BasicType)
from arith_op, and that's in as_jint(), which is called at line 1716 in
c1_LIRAssembler_aarch64.cpp.  The operand in question is a constant.  The
only constant value in the "test" method is 5.  Why is it of type long?
