Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446

Fix for ARM: functions don't have extra attributes there, so {{.*}} is "" While there, explicitly declare functions to remove warnings. llvm-svn: 175384

Add stack protector support to clang. This generates the 'ssp' and 'sspreq' function attributes. There are predefined macros that are defined when stack protectors are used: __SSP__=1 with -fstack-protector and __SSP_ALL__=2 with -fstack-protector-all. llvm-svn: 74405

Speed up testing by avoiding stdio.h, also helps testing on windows. Patch by John Thompson. llvm-svn: 83593
