c7e6b8fed5 Diagnostic for undefined assembler local symbols. 
Re-apply 133010, with fixes for inline assembler.

Original commit message:
"When an assembler local symbol is used but not defined in a module, a
Darwin assembler wants to issue a diagnostic to that effect."

Added fix to only perform the check when finalizing, as otherwise we're not
done and undefined symbols may simply not have been encountered yet.

Passes "make check" and a self-host check on Darwin.

ed1da49673 Revert 133010. Self-hosted buildbot unhappy. 
Apparently llvm itself generates undefined assembler local labels, causing
self-hosting problems with this patch. Reverting until that's sorted out.

dac0238ed2 .cfi directive register parsing flexibility. 
Parsing a register name/number for .cfi directives can't assume that a
register name starts with a '%' token. Be more flexible and check for a
register number instead. Still unlikely to be perfect, but it allows us
to parse both plain identifiers as register names and integers as register
numbers, which is what we're wanting to support at this point.

104af0619e To avoid printing out multiple error messages for cases like: 
.long 80+08

go ahead and assume that if we've got an Error token that we handled it
already. Otherwise if it's a token we can't handle then go ahead and
return the default error.

0c03a3a146 Revert r125595, which is an X86-only undocumented assembly syntax extension 
enabled for all targets. Non-X86 targets should not have this behavior
enabled by default.

Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.
