    Tested on top-of-tree `lldb`

Given the following code (the complicated part is just to avoid optimization)
```c
#include "stdint.h"
struct a {
  signed b : 2;
} c;
int d, e;
int f[1][10][10];
static int func_2(struct a g) {
  int8_t h = -24;
  uint64_t *i = (uint64_t*)&d;
  int32_t *j = (uint32_t*)f;
  int8_t *l_115;
  int8_t **k = &l_115;
  int32_t l = e = g.b | (*i = 9);
  *j = (l = j && ((*k = &h) || 7) << f[1][2][7]) && *j;
}
int main() { func_2(c); }
```

Compile it with `gcc -O1 -g`

The DWARF information generated for `l_115` will be a DW_OP_implicit_pointer, which `lldb` seems not being able to decode.
It generates the following error
> error: error: Couldn't materialize: couldn't get the value of variable l_115: Could not evaluate DW_OP_implicit_pointer.
error: errored out in DoExecute, couldn't PrepareToExecuteJITExpression

`gdb` can correctly recognize DW_OP_implicit_pointer and output the value of `*l_115=-24`
