cet-notrack-1.s

g++.dg/cet-notrack-1.C Tries to find 'call puts()' in the asm after calling
printf() on the c++ side.  On Mingw, we do magic things with converting
printf() into __mingw_ variants to support MS style printf and other things. 
So the assembler dump on mingw results in a call to __mingw_vfprintf in this
particular case.

It would likely be possible to fix the testcase by searching for "call
__mingw_*printf" or something, but I'm curious if this is really a case of a
missed optimization.  The strings in question are simple string literals, so we
don't care about mingw or ms special versions of printf, and a call to puts
should be fine.  I don't know if this testcase is specifically trying to
validate that optimization, but it at least indirectly revealed it.

Asm attached.
