[RenderScript] Remove mips specific expressions

Reverts earlier commit r254910, which used function pointers for jitted expressions
to avoid a Mips64 compiler bug. Bug has since been fixed, and compiler longer issues the problem instruction.

// Temporary workaround for MIPS, until the compiler emits the JAL instruction when invoking directly the function.
// At the moment, when evaluating an expression involving a function call, the LLVM codegen for Mips emits a JAL
// instruction, which is able to jump in the range +/- 128MB with respect to the current program counter ($pc). If
// the requested function happens to reside outside the above region, the function address will be truncated and the
// function invocation will fail. This is a problem in the RS plugin as we rely on the RS API to probe the number and
// the nature of allocations. A proper solution in the MIPS compiler is currently being investigated. As temporary
// work around for this context, we'll invoke the RS API through function pointers, which cause the compiler to emit a
// register based JALR instruction.
