MC/X86: Add "support" for matching ATT style mnemonic prefixes. - The idea is that when a match fails, we just try to match each of +'b', +'w', +'l'. If exactly one matches, we assume this is a mnemonic prefix and accept it. If all match, we assume it is width generic, and take the 'l' form. - This would be a horrible hack, if it weren't so simple. Therefore it is an elegant solution! Chris gets the credit for this particular elegant solution. :) - Next step to making this more robust is to have the X86 matcher generate the mnemonic prefix information. Ideally we would also compute up-front exactly which mnemonic to attempt to match, but this may require more custom code in the matcher than is really worth it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103012 91177308-0d34-0410-b5e6-96231b3b80d8 2010-05-04 16:12:42 +00:00			`// RUN: llvm-mc -triple x86_64 -o - %s \| FileCheck %s`
