Implement MipsSERegisterInfo::eliminateCallFramePseudoInstr. The function emits
instructions that decrement and increment the stack pointer before and after a
call when the function does not have a reserved call frame.

Implement MipsJITInfo::replaceMachineCodeForFunction.

No new test case is added.
This patch makes test JITTest.FunctionIsRecompiledAndRelinked pass on mips
platform.

Initial commit of new FileOutputBuffer support class.  
Since the llvm::sys::fs::map_file_pages() support function it relies on
is not yet implemented on Windows, the unit tests for FileOutputBuffer 
are currently conditionalized to run only on unix.

Add more indirection to the disassembler tables to reduce amount of space used to store the operand types and encodings. Store only the unique combinations in a separate table and store indices in the instruction table. Saves about 32K of static data.

Add basic in-bounds asserts to TinyPtrVector::erase.

Add range erase, element insert, and range insert methods to
TinyPtrVector. With these, it is sufficiently functional for my more
normal / pedestrian uses.

I've not included some r-value reference stuff here because the value
type for a TinyPtrVector is, necessarily, just a pointer.

I've added tests that cover the basic behavior of these routines, but
they aren't as comprehensive as I'd like. In particular, they don't
really test the iterator semantics as thoroughly as they should. Maybe
some brave soul will feel enterprising and flesh them out. ;]

Stay rational; don't assert trying to take the square root of a negative value.
If it's negative, the loop is already proven to be infinite. Fixes PR13489!
