John Criswell 44375ca7d6 Added a description of the algorithm. 
Return failure if the chmod() fails.

John Criswell 06327da723 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.

John Criswell 5357283c7a Added the MakeFileExecutable() method. This method takes a filename and 
gives it execute access while respecting the user's umask.

Chris Lattner ce35f14050 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

Chris Lattner 99b9ddead7 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

Chris Lattner e0703ff161 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.  :)

well put them INTO the auto-par pass.

Chris Lattner 8ef1b88aef Change the RaiseAllocations pass to be a Pass instead of a BasicBlock pass. 
This makes it more efficient: it doesn't have to scan the whole program, so
it performs work proportional to the number of malloc/free calls in the
program, not the size of the program.
