[llvm-dwarfdump] Display DW_AT_high_pc as absolute value
DWARF4 relative DW_AT_high_pc values are now displayed as absolute
addresses. The relative value is only shown when explicitly dumping the
forms, i.e. in show-form or verbose mode.
```
DW_AT_low_pc (0x0000000000000049)
DW_AT_high_pc (0x00000019)
```
becomes
```
DW_AT_low_pc (0x0000000000000049)
DW_AT_high_pc (0x0000000000000062)
```
