This patch solves a problem with passing varargs parameters under the PPC64
ELF ABI.

A varargs parameter consisting of a single-precision floating-point value,
or of a single-element aggregate containing a single-precision floating-point
value, must be passed in the low-order (rightmost) four bytes of the
doubleword stack slot reserved for that parameter.  If there are GPR protocol
registers remaining, the parameter must also be mirrored in the low-order
four bytes of the reserved GPR.

Prior to this patch, such parameters were being passed in the high-order
four bytes of the stack slot and the mirrored GPR.

The patch adds a new test case to verify the correct code generation.

This patch is for the implementation of mips16 complex pattern addr16.
Previously mips16 was sharing the pattern addr which is used for mips32
and mips64. This had a number of problems:
1) Storing and loading byte and halfword quantities for mips16 has particular
problems due to the primarily non mips16 nature of SP. When we must
load/store byte/halfword stack objects in a function, we must create a mips16
alias register for SP. This functionality is tested in stchar.ll.
2) We need to have an FP register under certain conditions (such as
dynamically sized alloca). We use mips16 register S0 for this purpose.
In this case, we also use this register when accessing frame objects so this
issue also affects the complex pattern addr16. This functionality is
tested in alloca16.ll.

The Mips16InstrInfo.td has been updated to use addr16 instead of addr.

The complex pattern C++ function for addr has been copied to addr16 and

LoopIdiom: Replace custom dependence analysis with DependenceAnalysis.

Requires a lot less code and complexity on loop-idiom's side and the more
precise analysis can catch more cases, like the one I included as a test case.
This also fixes the edge-case miscompilation from PR9481.

Compile time performance seems to be slightly worse, but this is mostly due
to an extra LCSSA run scheduled by the PassManager and should be fixed there.
