Bug ID: 44266
Summary: Function resolution should follow the same rule in
global context as function body.
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: CUDA

resolution under function gets the correct host function
In the following sample code
```
__device__ float fn(int);
__host__ float fn(float);
float gvar = fn(1);
```
clang failed to find the correct candidate of `fn`. But, if we modify that to
resolve `fn` under a function body. The correct one is used.
```
__device__ float fn(int);
__host__ float fn(float);
float gfunc() {
return fn(1);
}
```
For function resolution in (host-side) global initializers, we should follow
the same rule as the one under a function body.
