Extended Description

llvm/test/FrontendC/2007-06-15-AnnotateAttribute.c has a comment that reads:
// RUN: %llvmgcc -S %s -o - | grep llvm.global.annotations
// RUN: %llvmgcc -S %s -o - | grep llvm.var.annotation | count 3

When I run the following I get no output of any kind:
"clang -emit-llvm -S 2007-06-15-AnnotateAttribute.c -o - | grep llvm.var.annotation"

The following does seem to function correctly:
"clang -emit-llvm -S 2007-06-15-AnnotateAttribute.c -o - | grep llvm.global.annotation"

It outputs:
@​llvm.global.annotations = appending global [2 x { i8*, i8*, i8*, i32 }] [{ i8*, i8*, i8*, i32 } { i8* bitcast (i32* @​main.a to i8*), i8* getelementptr inbounds ([20 x i8]* @​main.a1, i32 0, i32 0), i8* getelementptr inbounds ([31 x i8]* @.str, i32 0, i32 0), i32 20 }, { i8*, i8*, i8*, i32 } { i8* bitcast (i32* @​X to i8*), i8* getelementptr inbounds ([20 x i8]* @​X3, i32 0, i32 0), i8* getelementptr inbounds ([31 x i8]* @.str4, i32 0, i32 0), i32 7 }], section "llvm.metadata"

I attached the output of
"clang -emit-llvm -S 2007-06-15-AnnotateAttribute.c"

Note that llvm-gcc does produce the local annotations.

clang: Don't use grep in a test
d7fcb5b 
Issue #10894 seems to claim this wasn't working. The test does seem to
work as intended, except the CHECKs added in
3ac4299 aren't doing anything since
it wasn't really using FileCheck.

I believe this is working correctly, I've switched the test to using FileCheck
