Fix a div-by-zero bug noticed by APInt. This fixes:
test/Transforms/IndVarsSimplify/exit_value_tests.llx

This test was failing because of signlessness and a difference in the
way the AsmWriter prints arguments.

Rewrite the upgrade of GEP indices to be a little less obtuse. This fixes

1. Don't bother truncating reading of the file. It doesn't save that much
time and we should support putting RUN lines anywhere in the file. For
example, someone might want to put the grep match before each function
in the test file which would sprinkle the RUN: lines throughout the file.
2. Fix a bug with llvmgcc version match .. global var wasn't declared as such

1. Only read the first 1024 bytes of the file. The RUN: lines should all be
within that amount of space. This keeps I/O costs down when reading
very large files.
2. Print PR numbers with a PR prefix so it is clear what they are.

Upgrade to new Tcl exec based test framework. This exposes three regressions
in llvm-upgrade:
test/Assembler/2002-08-19-BytecodeReader.llx
test/Assembler/2003-08-21-ConstantExprCast-Fold.llx
test/Assembler/2004-01-11-getelementptrfolding.llx

Upgrade to use new Tcl exec based test harness. This exposes 3 bugs that
were previously not being reported:
test/Transforms/GlobalDCE/2002-08-17-FunctionDGE.ll
test/Transforms/GlobalOpt/memset.ll
test/Transforms/IndVarsSimplify/exit_value_tests.llx

constructing ImmediateDominator is now folded into DomTree construction.
This is part of the ongoing work for PR217.

Make use of the END. facility on all files > 1K so that we aren't wasting CPU
cycles searching for RUN: lines that we'll never find.

the "check-one" target. This was necessitated by the change in the test
harness to fully use Tcl's "exec" function and avoid shell scripts
altogether. Consequently, to be accurate, TestRunner.sh needs to invoke the
same environment as dejagnu would, but for just a single test. That's what
the make target "check-one" does so we just invoke it here.
