its callers to emit a space character before calling it when a space is needed. This fixes several spurious whitespace issues in ScalarEvolution's debug dumps. See the test changes for examples. This also fixes odd space-after-tab indentation in the output for switch statements, and changes calls from being printed like this: call void @foo( i32 %x ) to this: call void @foo(i32 %x) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56196 91177308-0d34-0410-b5e6-96231b3b80d8
