Subzero: Clean up function header emission.
1. Don't do anything in Cfg::emitTextHeader() in MINIMAL mode. (Reduces binary size by 1KB.) This actually broke a number of lit tests for the MINIMAL build, so "--assemble --disassemble" was changed to "--filetype=obj --disassemble". This allowed (or required) better precision in checking for data symbols.
1a. For the lit files touched, go ahead and remove "-verbose none" since that will forevermore by the default.
2. Don't emit the ".bundle_align_mode" directive. This is not
necessary when assembling with the right -triple argument.
