Vector Pascal Compiler Code

in process of converting AVX64 to use nasm, this requires
a change to i386base to allow it optionally include 64 bit regs

check for heap allocate deallocate

Update the 64 bit version to allow conditional expressions with 32 bit reals, and add test program for that

These are corrections necessary to pass some of the acceptance tests

fixed order of AVX64 but not yet efficient

reorder instructions in avx64 priority

still problems with boolean ops on reals in AVX64

first run of avx64
