Implement enough of the missing instalias support to get
...
aliases installed and working. They now work when the
matched pattern and the result instruction have exactly
the same operand list.
This is now enough for us to define proper aliases for
movzx and movsx, implementing rdar://8017633 and PR7459.
Note that we do not accept instructions like:
movzx 0(%rsp), %rsi
GAS accepts this instruction, but it doesn't make any
sense because we don't know the size of the memory
operand. It could be 8/16/32 bits.

Be more strict on when we produce an undefined reference. In gas a file with
...
just
.type foo,@object
will produce an undefined reference to foo. On the other hand, a file with
just
.weakref bar, foo
will not. It is somewhat hard to support both in MC since both statements
should create the symbols. It should be possible if we really need to by
adding to the flags, but hopefully that is not necessary.
With this patch we do not produce a undefined reference in any of those cases.
The assembly file needs an actual use for the undefined reference to be
present.
This is in preparation for a patch implementing .weakref.

the beginning ended and don't go past that point when counting duplicates

This change causes one of the MC/ARM/simple-fp-encoding tests to produce
different (better!) code without the vmovne instruction being tested.
I changed the test to produce vmovne and vmoveq instructions but moving
between register files in the opposite direction. That's not quite the same
but predicated versions of those instructions weren't being tested before,
so at least the test coverage is not any worse, just different.
