b22c819f96 Fix (and properly doxygenify) some comments. Incorporate 
functionality of FunctionInfo pass as doFinalization method.
Rename pass to match names of other passes like it.
Rename the pass creator fn to mimic the other creator fn names.
Include StringExtras for utostr().
Make symbol prologue/epilogue stuff redundant with
 EmitBytecodeToAssembly, in preparation for refactoring.

e1ccc5a286 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.

4d934ceefa 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...

8502d4f3f8 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.

ebf6d5c622 Rework dominator interfaces to handle changes in the post-dominance 
construction.  Now there may be multiple root blocks, and null is a
special node used to mark the "virtual" exit node of a CFG.

9d9fd138dc 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. :)
