Add PGAC_PROG_VARCC_VARFLAGS_OPT autoconf macro.
The new macro allows to test flags for different compilers and tostore them in different CFLAG like variables. The existingPGAC_PROG_CC_CFLAGS_OPT and PGAC_PROG_CC_VAR_OPT are changed to bejust wrappers around the new function.This'll be used by the upcoming LLVM support, to separately detectcapabilities used by clang, when generating bitcode.Author: Andres FreundDiscussion:https://postgr.es/m/20170901064131.tazjxwus3k2w3ybh@alap3.anarazel.de
