fbc927711a Add a WHOLE lot of updates clarifications and fixes. This is not done but getting closer. I changed the docs to reflect the goal of making unwind an instruction, not an intrinsic.

e4adff8157 Removal of explicit stack, which requires the method to be a member (so it can
call setAbstract).  Now that we just compute abstractness we can also return
the computed value by value instead of as an argument.

05eecdb7de Remove the "recursive bit", not only is it unused by anyone, it was also
not correctly calculated, and calculating it wrong for fun seems rather
pointless.  This also speeds up my favorite testcase by .25 seconds.

cdcee99ee6 Added code that makes the bytecode file readable (needed by the generated shell
script).
Removed the use of sys/types.h and sys/stat.h.
Modified FileExists() so that it uses the access() system call to check for
file existance.  This requires less header files and might even be a tad bit
faster.

3ac81b74cb Modified the code so that it uses the MakeFileExecutable() method. The new
library code now adds all execute bits that are allowed by the umask value to
the file's current permission bits.

7b83fe6beb Added the MakeFileExecutable() method. This method takes a filename and
gives it execute access while respecting the user's umask.

590606e4c4 Don't bother doing an exhaustive recursive walk if we are at the limit of what
we need to know anyway.  This reduces the 2002-07-08-HugePerformanceProblem.llx
down to 3.210u:0.010s, which is back in the acceptable range again

06d8aac065 Ugh, fix bugs. Ok, so the last fix wasn't as great as I thought it was.
Now we're back to: 131.730u, 0.330s, which is still quite an improvement,
but still quite unacceptable

dda7669997 Change the code to no longer compute the "type description" immediately when
the type is analyzed.  Instead, only compute it when requested (with
getDescription), and cached for reuse later.

This dramatically speeds up LLVM in general because these descriptions almost
_never_ need to be constructed.  The only time they are used is when a type is
<<'d.  Printing of modules by themselves uses other code to print symbolic
types when possible, so these descriptions are really only used for debugging.

Also, this fixes the particularly bad case when lots of types get resolved to
each other, such as during linking of large programs.  In these cases, the type
descriptions would be repeatedly recomputed and discarded even though: A. noone
reads the description before it gets resolved, and B. many many resolutions
happen at intermediate steps, causing a HUGE waste of time.

Overall, this makes the getTypeDesc function much more light-weight, and fixes
bug: Assembler/2002-07-08-HugePerformanceProblem.llx, which went from taking
1048.770u/19.150s (which is 17.5 MINUTES, on apoc), to taking 0.020u/0.000s,
which is a nice little speedup.  :)
