Changes in directory llvm-test:
configure updated: 1.20 -> 1.21
Makefile.config.in updated: 1.15 -> 1.16
---
Log message:
Test for the re_comp function so that platform differences can be
compensated for via testing in makefiles if HAVE_RE_COMP is defined. With
this change, llvm-test makefiles can do something like:
ifdef HAVE_RE_COMP
...
endif
