Committing many changes - most importantly: Opincaa program and simulator take number lanes, registers, etc from command line

• Committing many changes, most importantly: Opincaa program and simulator accept from command line number of lanes, number of registers, LS mem size, instruction queue length.
• See README_Alex for most recent changes:
  • made Opincaa library (runtime assembler and simulator) allow for lanes other types than i16 (short) or u16, such as i32 (int) - added in arch/connex16-hm-generic/include/Architecture.h the typedef of TYPE_ELEMENT, etc.
  • verified with Valgrind that the Opincaa program (not also the Opincaa simulator) does NOT have any memory leaks or invalid reads.
  • worked on improving the assembly time of Opincaa kernels
  • corrected operators that were NOT working properly in simulator
  • added ConnexMachine::writeDataToConnexPartial() and ConnexMachine::readDataFromConnexPartial()
  • added support for OpincaaLLVM compiler automatic Instruction Selection code generation from Opincaa kernels - see method Kernel::genLLVMISelManualCode()
  • added a few new instructions to simulator:
    • for debugging: _PRINT_REG, _PRINT_CHARS and the macrodefs PRINTREG(), PRINTCHARS() and PrintDebugMessage(), PrintRegDebug()
    • experimental: _SETLC_REDUCE, _BIT_REVERSE and the macrosdefs REPEAT_REDUCE and BITREVERSE
  • better indentation for the source files
  • various other small corrections
