Between 20190514 (r271183) and 20190515 (r271254), a single D testcase started
to FAIL on both 32-bit Solaris/SPARC and x86:

+FAIL: gdc.test/runnable/mars1.d -O2   (internal compiler error)
+FAIL: gdc.test/runnable/mars1.d -O2 -finline-functions   (internal compiler
error)

In function 'test14782':
d21: error: address taken, but ADDRESSABLE bit not set
PHI argument
&result;
for PHI node
_21 = PHI <&result(2), _22(4)>
during GIMPLE pass: einline
