Imagine we have a broken .eh_frame.
Below is a possible sample output of llvm-readelf:
```
...
entry 2 {
initial_location: 0x10f5
address: 0x2080
}
}
}
.eh_frame section at offset 0x2028 address 0x2028:
LLVM ERROR: Parsing entry instructions at 0 failed
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.

Aborted
```
I.e. it calls abort(), suggests to submit a bug report and exits with the code 134.
This patch changes the logic to propagate errors to callers.
This fixes the behavior for llvm-dwarfdump, llvm-readobj and other possible tools.
