Bug 22087 – `synchronized scope(exit) <statement>`: statement is skipped

The following utterly fails - `i++` isn't executed: ``` int i; void foo() { synchronized scope(exit) i++; } void main() { foo(); assert(i == 1); } ``` The generated asm is terrible - there are 2 (!) additions *after* ret: ``` void onlineapp.foo(): push RBP mov RBP,RSP sub RSP,010h mov qword ptr -8[RBP],0 mov RDI,shared(void*) onlineapp.foo().__critsec2@GOTPCREL[RIP] call _d_criticalenter2@PLT32 mov RAX,shared(void*) onlineapp.foo().__critsec2@GOTPCREL[RIP] mov RDI,[RAX] call _d_criticalexit@PLT32 leave ret add [RAX],AL add [RAX],AL ``` --- What works is an explicit block: `synchronized { scope(exit) i++; }`.
