d752e0f7e6 Added invariant field to the DAG.getLoad method and changed all calls. 
When this field is true it means that the load is from constant (runt-time or compile-time) and so can be hoisted from loops or moved around other memory accesses

ad6eef4a65 This patch handles unaligned loads and stores in Mips JIT. Mips backend 
implements unaligned loads and stores with assembler macro-instructions
ulw, usw, ulh, ulhu, ush, and this patch emits corresponding instructions
instead of these macros. Since each unaligned load/store is expanded
into two corresponding loads/stores where offset for second load/store is
modified by +3 (for words) or +1 (for halfwords).

Patch by Petar Jovanovic and Sasa Stankovic.

c3f16b316a Final patch that completes old JIT support for Mips: 
-Fix binary codes and rename operands in .td files so that automatically
generated function MipsCodeEmitter::getBinaryCodeForInstr gives correct
encoding for instructions.
-Define new class FMem for instructions that access memory.
-Define new class FFRGPR for instructions that move data between GPR and
FPU general and control registers.
-Define custom encoder methods for memory operands, and also for size
operands of ext and ins instructions.
-Only static relocation model is currently implemented.

da7f5f1c1d Make changes to avoid creating nested CALLSEQ_START/END constructs, which aren't 
yet legal according to comments in LegalizeDAG.cpp:227. 

Memcpy nodes created for copying byval arguments are inserted before
CALLSEQ_START.

The two failing tests reported in PR10876 pass after applying this patch.

c4cc40c001 One more patch towards JIT support for Mips. 
- Add TSFlags for the instruction formats. The idea here is to use
  as much encoding as possible from getBinaryCodeForInstr, and having
  TSFLags formats for that would make it easier to encode most part
  of the instructions (since Mips encodings are pretty straightforward)
- Improve the mips mechanism for compilation callback
- Add Mips specific code for invalidating the instruction cache
- Next patch will address wrong tablegen encoding

Commit msg added by my own but the patch is from Sasa Stankovic.
