LOG: [DebugLine] Correct debug line emittion (#157529)
### Context
#99710 introduced `.loc_label` so we can terminate a line sequence.
However, it did not advance PC properly. This is problematic for
1-instruction functions as it will have zero-length sequence. The test
checked in that PR shows the problem:
```
# CHECK-LINE-TABLE: Address Line Column File ISA Discriminator OpIndex Flags
# CHECK-LINE-TABLE-NEXT: ------------------ ------ ------ ------ --- ------------- ------- -------------
# CHECK-LINE-TABLE-NEXT: 0x00000028: 05 DW_LNS_set_column (1)
# CHECK-LINE-TABLE-NEXT: 0x0000002a: 00 DW_LNE_set_address (0x0000000000000000)
# CHECK-LINE-TABLE-NEXT: 0x00000035: 01 DW_LNS_copy
# CHECK-LINE-TABLE-NEXT: 0x0000000000000000 1 1 1 0 0 0 is_stmt
# CHECK-LINE-TABLE-NEXT: 0x00000036: 00 DW_LNE_end_sequence
# CHECK-LINE-TABLE-NEXT: 0x0000000000000000 1 1 1 0 0 0 is_stmt end_sequence
```
Both rows having PC 0x0 is incorrect, and parsers won't be able to parse
them. See more explanation why this is wrong in #154851.
### Design
This PR attempts to fix this by advancing the PC to the next available
Label, and advance to the end of the section if no Label is available.
### Implementation
- `emitDwarfLineEndEntry` will advance PC to the `CurrLabel`
- If `CurrLabel` is null, its probably a fake LineEntry we introduced in
#110192. In that case look for the next Label
- If still not label can be found, use `null` and
`emitDwarfLineEndEntry` is smart enough to advance PC to the end of the
section
- Rename `LastLabel` to `PrevLabel`, "last" can mean "previous" or
"final", this is ambigous.
- Updated the tests to emit a correct label.
### Note
This fix should render #154986 and #154851 obsolete, they were temporary
fixes and don't resolve the root cause.
