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.

afb36fad99 Restore r125595 (reverted in r126336) with modifications: 
Introduce a variable in the AsmParserExtension whether [] is valid in an
expression. If it is true, parse them like (). Enable this for ELF only.

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.

290d71671e Implement cfi_def_cfa. Also don't convert to dwarf reg numbers twice. Looks 
like 6 is a fixed point of that and so the previous tests were OK :-)

fa3c6f148c In llvm-mc parse a Hash token as a full line comment. Allows handling of

46c79ef113 Fix PR8565. 
This moves most of the isUsed logic to the MCSymbol itself. With this we
get a bit more relaxed about allowing definitions after uses: uses that
don't evaluate their argument immediately (jmp foo) are accepted.

ddunbar, this was the smallest compromise I could think of that lets us
accept gcc (and clang!) assembly.
