One of our internal tests started to hit an assertion failure which I bisected to be caused by commit bbeaf2a.
```
clang: /home/dyung/src/upstream/llvm_clean_git/llvm/include/llvm/ADT/SmallVector.h:277: T& llvm::SmallVectorTemplateCommon<T, <template-parameter-1-2> >::operator[](llvm::SmallVectorTemplateCommon<T, <template-parameter-1-2> >::size_type) [with T = llvm::Evaluator::MutableValue; <template-parameter-1-2> = void; llvm::SmallVectorTemplateCommon<T, <template-parameter-1-2> >::reference = llvm::Evaluator::MutableValue&; llvm::SmallVectorTemplateCommon<T, <template-parameter-1-2> >::size_type = long unsigned int]: Assertion `idx < size()' failed.
```
I also reduced the test to the following code:
```c++
void init(char, void *data, unsigned size) {
unsigned char *bytes = (unsigned char *)data;
for (unsigned i = 0; i != size; ++i)
bytes[i] = i;
}
#define INIT(PRED, VAR) init(PRED, &VAR, sizeof(VAR))
struct test3_struct_id696_ {
test3_struct_id696_() { INIT(8, *this); }
long : 36;
wchar_t b;
} test38_struct_id7952;
```
To reproduce the failure, compile the code with optimizations enabled (-O2) and targeting the PS4 (-target x86_64-scei-ps4):
```
clang -c -O2 -target x86_64-scei-ps4 repro.cpp
```
