Two changes:
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

Two improvements:

Reimplement in terms of the support for this feature in the makefiles with
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.

Extend store merging to support the 'if/then' version in addition to if/then/else.

This sinks the two stores in this example into a single store in cond_next.  In this
case, it allows elimination of the load as well:

        store double 0.000000e+00, double* @s.3060
        %tmp3 = fcmp ogt double %tmp1, 5.000000e-01             ; <i1> [#uses=1]
        br i1 %tmp3, label %cond_true, label %cond_next
cond_true:              ; preds = %entry
        store double 1.000000e+00, double* @s.3060
        br label %cond_next
cond_next:              ; preds = %entry, %cond_true
        %tmp6 = load double* @s.3060            ; <double> [#uses=1]

Changes to fix problems with "make check". Apparently you can redefine
functions and Tcl's just tickled with that. The fix is to give the "new"
test system a different interface function name.

Implement InstCombine/vec_demanded_elts.ll:test2.  This allows us to turn

unsigned test(float f) {

}

into:

_test:
        movss 4(%esp), %xmm0
        mulss %xmm0, %xmm0
        movd %xmm0, %eax
        ret

instead of:

_test:

        xorps %xmm1, %xmm1
        movss %xmm0, %xmm1

For PR1319:
More improvements:
1. Using ::errorInfo wasn't such a hot idea. Go back to just printing the
   offending line of code and the stderr output. This is sufficient and
   not entangled with Tcl goop.
2. Capture the problem report numbers and report them whether pass or fail.
   This helps quickly get some context when a test fails, if it has an
   associated PR number.
