Passed bootstrap/regtest, I've committed both -gcolumn-info patches; thanks
for review.
Comparing the cc1plus debug info sizes between standard bootstrap and
one with hacked default -gcolumn-info shows:
-gno-column-info (default):
[31] .debug_info PROGBITS 0000000000000000 1d9e948 5ae23f3 00
0 0 1
[32] .debug_abbrev PROGBITS 0000000000000000 7880d3b 1b1dac 00
0 0 1
[33] .debug_line PROGBITS 0000000000000000 7a32ae7 68ab1b 00
0 0 1
-gcolumn-info:
[31] .debug_info PROGBITS 0000000000000000 1d9e948 5d72ddb 00
0 0 1
[32] .debug_abbrev PROGBITS 0000000000000000 7b11723 1d9ec9 00
0 0 1
[33] .debug_line PROGBITS 0000000000000000 7ceb5ec 9bf412 00
0 0 1
All other sections have the same size.
So it is 2.8% growth in .debug_info, 9.2% growth in .debug_abbrev and 49%
growth in .debug_line.
