[mips] Make Static a default relocation model for MIPS codegen This change follows up defaults for GCC and Clang, so LLVM does not differ from them. While number of the test files are touched with this change, they all keep the old (expected) behaviour with the explicit option: "-relocation-model=pic" The tests that have not been touched are insensitive to relocation model.

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786. A similar migration script can be used to update test cases, though a few more test case improvements/changes were required this time around: (r229269-r229278) import fileinput import sys import re pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)") for line in sys.stdin: sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line)) Reviewers: rafael, dexonsmith, grosser Differential Revision: http://reviews.llvm.org/D7649 llvm-svn: 230794

[mips] For indirect calls we don't need $gp to point to .got. Mips linker doesn't generate lazy binding stub for a function whose address is taken in the program. Differential Revision: http://reviews.llvm.org/D5067 llvm-svn: 218744
