If `--enable-var-scope` is in effect, variables with names that start with `$` are considered to be global. All other variables are local. All local variables get undefined at the beginning of each CHECK-LABEL block. Global variables are not affected by CHECK-LABEL. This makes it easier to ensure that individual tests are not affected by variables set in preceding tests. Differential Revision: https://reviews.llvm.org/D30749 llvm-svn: 297396
