The modifications to LD_LIBRARY_PATH now add the specified paths to the

This allows users to use LD_LIBRARY_PATH when running tests (useful for
when they have installed their own version of GCC).

Rename many instructions to their Intel asm-compatible names. This
involves removing the [bwl] suffixes from instruction names, as well

take that, either.

The never-ending odyssey trying to get sparc to link

Do not link in the Sparc JIT when building on X86.  Eventually the sparc will not
link in the X86 JIT either, but this makes testing easier.

For some reason, the sparc JIT was breaking the X86 JIT when it was linked in. :(

Fairly major change: emit fixed sized allocas in the entry block as a variable,
instead of a variable pointer and an alloca.  All accesses to the variable then
use the address-of operator to access it.  This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.
