Rafael Auler	7a3e664db5	[DebugInfo] Do not error on unsupported CIE version D81469 introduced a check to error on CIE version different than 1 for eh_frame, but older compilers mistakenly create binaries with this version set to 3 for DWARF4 or 4 to DWARF5.

[DebugInfo] Do not error on unsupported CIE version

D81469 introduced a check to error on CIE version different
than 1 for eh_frame, but older compilers mistakenly create binaries
with this version set to 3 for DWARF4 or 4 to DWARF5. Move the check
to dump time instead of eh_frame parse time, so we can be tolerant
with older binaries.

[DebugInfo/DWARF] - Report .eh_frame sections of version != 1.

Specification (https://refspecs.linuxbase.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/ehframechpt.html#AEN1349)
says that the value of Version field for .eh_frame should be 1.

Though we accept other values and might perform an attempt to read
it as a .debug_frame because of that, what is wrong.

This patch adds a version check.
