Subject: 1. No need to thwart this test with an environment variable. Turning it off
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=226368ff4e530d16b9368ec1ad2b41fbe9182b0f;p=oota-llvm.git

1. No need to thwart this test with an environment variable. Turning it off
   is the default and handled by the makefile system and runtest
2. Redirect stderr of llvm-as and llvm2cpp so that warning messages about
   instrinsics don't cause Tcl to report the run as failed.
