testcase

Noticed while compiling src/deps_log.cc ninja 1.10.2 on hppa. I trimmed down
the file to test.cc.

g++ -O2 -c ./test.cc -o test.o
./test.cc: In member function 'LoadStatus DepsLog::Load(const string&, Stat=
e*,
std::__cxx11::string*)':
./test.cc:176:1: error: unrecognizable insn:

            (const_int -524292 [0xfffffffffff7fffc]))) "./test.cc":122 -1
