Fix generation of 'isa' and 'discriminator' keywords. Summary: There should be a space before each of these two keywords to avoid generating invalid assembly files. NOTE: I could not find an obvious maintainers in CODE_OWNERS.TXT, but this seems related to debug info.

Parse and remember discriminators in .loc line. I try to output them with another patch. This lets us parse a bit more of the gcc 4.5 output. llvm-svn: 118975

MCParser/Debug info: Accept line number 0 as a legitimate value, since CFE produces it to indicate artificial locations. c.f.: DWARF standard, Table 6.2: line -- An unsigned integer indicating a source line number. Lines are numbered beginning at 1. The compiler may emit the value 0 in cases where an instruction cannot be attributed to any source line. llvm-svn: 191471
