Fix for aggregate copying of variable length arrays.
Patch fixes codegen for aggregate copying of VLAs. Currently method CodeGenFunction::EmitAggregateCopy() does not support copying of VLAs. Patch checks if the size of the type is 0, then checks if the type is actually a variable-length array. Then it calculates total length for this array and calculates total size of the array in bytes:
<total number of elements in array> * aligned_sizeof(ElementType) (if copy assignment is requested).
If simple copying is requested, size is calculated like:
<total number of elements in array> * aligned_sizeof(ElementType) - aligned_sizeof(ElementType) + sizeof(ElementType).
memcpy() is used with this calculated size of the VLA.
