Vyacheslav Egorov 3da9c349d4 [vm/simarm] Fix VRECPS/VRSQRTSQS instruction implementation. 
This instruction handles 0.0 and infinity operands
specially because otherwise it produces NaN where it
should produce appropriate infinity or zero.

Vyacheslav Egorov 8a179fb953 [VM, Compiler] Move compiler to a separate folder. 
New folder structure (nested under vm/):

- compiler/
-   jit/         - JIT specific code
-   aot/         - AOT specific code
-   backend/     - all middle-end and back-end code (IL, flow graph)
-   assembler/   - assemblers and disassemblers
-   frontend/    - front ends (AST -> IL, Kernel -> IL)

compiler/README.md would be the documentation root for the compiler
pipeline
