Summary:
This patch allows to resolve a symbol context block info even if a function
info was not requested. Also it adds the correct resolving of nested blocks
(the previous implementation used function blocks instead of them).

Summary:
This patch fixes a problem with retrieving a function symbol by an address in a nested block. In the current implementation of ResolveSymbolContext function it retrieves a symbol with PDB_SymType::None and then checks if found symbol's tag equals to PDB_SymType::Function. So, if nested block's symbol was found, ResolveSymbolContext does not resolve a function.
It is very simple to reproduce this. For example, in the next program
```
int main() {
auto r = 0;
for (auto i = 1; i <= 10; i++) {
r += i & 1 + (i - 1) & 1 - 1;
}
return r;
}
```
if we will stop inside the cycle and will do a backtrace, the top element will be broken. But how we can test this? I thought to add an option to lldb-test to allow search a function by address, but the address may change when the compiler will be changed.
