8012715: G1: GraphKit accesses PtrQueue::_index as int but is size_t Summary: In graphKit INT operations were generated to access PtrQueue::_index which has type size_t. This is 64 bit on 64-bit machines. No problems occur on little endian machines as long as the index fits into 32 bit, but on big endian machines the upper part is read, which is zero. This leads to unnecessary branches to the slow path in the runtime. Reviewed-by: twisti, johnc Contributed-by: Martin Doerr <martin.doerr@sap.com>

# Note: When indented, make tries to execute the '$(shell' comment.
# In some environments, cmd processors have limited line length.
# To prevent the javac invocation in the next block from using
# a very long cmd line, we use javac's @file-list option. We
# generate the file lists using make's built-in 'foreach' control
# flow which also avoids cmd processor line length issues. Since
# the 'foreach' is done as part of make's macro expansion phase,
# the initialization of the lists is also done in the same phase
# using '$(shell rm ...' instead of using the more traditional
