[PATCH 21/61] Testsuite: Modify the gcc.dg/memcpy-4.c test
From: Andrew Bennett <andrew.benn...@imgtec.com>
Firstly, remove the MIPS specific bit of the test.
Secondly, create a MIPS specific version in the gcc.target/mips.
This will only execute for a MIPS ISA less than R6.
Cherry-picked c8b051cdbb1d5b166293513b0360d3d67cf31eb9

* gcc.dg/memcpy-4.c: Remove mips specific code.
* gcc.target/mips/memcpy-2.c: New test.
