Extended Description

clang is not able to codegen break/return/continue when called from a scope with VLA's

witten /tmp# ccc vla.c
vla.c:9:3: error: cannot codegen this break inside scope with VLA yet
break;
^~~~~
vla.c:12:3: error: cannot codegen this continue inside scope with VLA yet
continue;
^~~~~~~~
vla.c:16:4: error: cannot codegen this return inside scope with VLA yet
return;
^~~~~~
3 diagnostics generated.

the attached vla.c demonstrates this problem

Ah, it would be very nice to at least handle the case where the break/continue doesn't leave the vla scope, as in the example.

[llvmbot]

It would be nice to handle

void f(int x) { int a[x]; return; }

too. :)

this seems to be fixed, I am able to compile the test without problems
