95f0c9ffc7 [MIPS][microMIPS] Enable dynamic stack realignment
Dynamic stack realignment was disabled on micromips by checking if
target has standard encoding. We simply change the condition to skip
Mips16 only.

d2c18d6b60 [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.

330e5f16d1 [mips] Add support for dynamic stack realignment.
Summary:
With this change we are able to realign the stack dynamically, whenever it
contains objects with alignment requirements that are larger than the
alignment specified from the given ABI.

We have to use the $fp register as the frame pointer when we perform
dynamic stack realignment. In complex stack frames, with variably-sized
objects, we reserve additionally the callee-saved register $s7 as the
base pointer in order to reference locals.
