r195676 - Make the integrated assembler the default for cygwin/mingw too.

[Yaron Keren]

With svn clang and MingW 4.8.1 the integrated assembler breaks C++
exceptions.
Example:
#include <stdio.h>
int main() {
  try {
    throw 1.0;
  }
  catch (...) {
    printf("Caught.\n");
  }
  return 0;
}

Compiled with:
clang t.cpp -o t.exe -g -target i686-pc-mingw32 -nostdinc
-Ic:\mingw-builds\x32-4.8.1-win32-dwarf-rev5\mingw32\i686-w64-mingw32\include\
-Wno-deprecated-register -Wno-ignored-attributes -lstdc++

Results in:
terminate called after throwing an instance of 'double'
