[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.

[mips] Enable tail calls by default Enable tail calls by default for (micro)MIPS(64). microMIPS is slightly more tricky than doing it for MIPS(R6) or microMIPSR6. microMIPS has two instruction encodings: 16bit and 32bit along with some restrictions on the size of the instruction that can fill the delay slot. For safe tail calls for microMIPS, the delay slot filler attempts to find a correct size instruction for the delay slot of TAILCALL pseudos.

[mips] do not use FastISel when -mxgot is present The clang compiler by default uses FastISel when invoked with -O0, which is also the default. In that case, passing of -mxgot does not get honored, i.e. the code path that is to deal with large got is not taken. Clang produces same output regardless of -mxgot being present or not. This change checks whether -mxgot is passed as an option, and turns off FastISel if it is. Patch by Stefan Maksimovic. Differential Revision: https://reviews.llvm.org/D33593 llvm-svn: 304906

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction Essentially the same as the GEP change in r230786.
