smaller testcase

Here's a smaller testcase, that just needs two input files
(but uniset.ii still needs its gcda file):

markus@x4 lto_pgo_testcase % cat unorm.ii
namespace icu_50 {
class UnicodeString {
 public:
  UnicodeString();
  void extractBetween(int, int, unsigned short *, int = 0) const;
  void doExtract(int, unsigned short *, int) const;
  void pinIndex(int &) const;
};
inline void UnicodeString::extractBetween(int p1, int p2, unsigned short *p3,
                                          int p4) const {
  pinIndex(p1);
  doExtract(p2 - p1, p3, p4);
}
UnicodeString::UnicodeString() { extractBetween(0, 0, 0); }
UnicodeString a;
}

markus@x4 lto_pgo_testcase % g++ -g -fPIC -flto -fno-exceptions -O2 -std=c++11
-c unorm.ii
markus@x4 lto_pgo_testcase % g++ -w -g -fprofile-use -fPIC -flto
