e5b3e1559b In ExecWait(), made the child process exit if it can't execve() the new
program.
Added the use of const (which compiles and is hopefully correct).
Added comments.

5afb5f6377 Added the ExecWait() function. It executes a program with the specified
arguments and environment.
Perhaps it should be merged with the RunProgramWithTimeout function, but I'd
want to allow it to inherit the parent process's stdin and stdout.
I'll save that for a rainy day...

Thanks to brg for tracking down the problem so precisely!

1cbcd0fd48 This is effectively a complete rewrite of the globaldce algorithm, resulting
in it being both shorter and more effective.  It no longer depends on the
callgraph, so one FIXME has been fixed.

Additionally, this pass was not able to delete recursive (but dead) functions
if they were pointed to by global variables which were also dead.  In fact
this pass had a lot of problems deleting functions which were only pointed
to by dead globals and other stuff.

Fixing this means that the entire EH library should be stripped away now from
programs that don't use sjlj or exceptions.

706e61ead9 Rework post dominator information so that we do not have to
unify all exit nodes of a function to compute post-dominance information.
This does not work with functions that have both unwind and return nodes,
because we cannot unify these blocks.  The new implementation is better
anyway. :)
