MIPS64: Improve string and class loads.
This adds most kinds of string/class loads.
JIT string/class loads are TBD separately.
This also fixes Mips64Assembler::LoadLabelAddress()
(adding a constant to a 64-bit address must be done
using daddiu, not addiu).
Test: test-art-host-gtest
Test: booted MIPS64 (with 2nd arch MIPS32R6) in QEMU
Test: "make -j1 ART_TEST_DEFAULT_COMPILER=false ART_TEST_OPTIMIZING=true
ART_TEST_INTERPRETER=false ART_TEST_JIT=false
ART_TEST_PIC_TEST=true test-art-target-run-test64"
