Aleksandr Urakov 758657e565 [PDB] Fix location retrieval for function local variables and arguments that are
stored relative to VFRAME

Summary:
This patch makes LLDB able to retrieve proper values for function arguments and
local variables stored in PDB relative to VFRAME register.

Patch contains retrieval of corresponding FPO table entries from PDB and a
generic translator from FPO programs to DWARF expressions to get correct VFRAME
value.

Patch also improves variables-locations.test and makes this test passable on
x86.
