Remove x87 code generation from opt compiler.

Details

Description

We have migrated to SSE code generation on IA32 but x87 code generation remains for older architectures. Generating code for the x87 FPU stack is quite complex and has particularly complicates the register allocator. We should remove this support to the point where we can just do very simple code generation for x87.
