We were dropping the displacement on the floor if we also had some
immediate offset.
Should fix PR19033.

The .error directive is similar to .err in that it will halt assembly if it is
evaluated for assembly. However, it permits a user supplied message to be
rendered.

The .ifeqs directive assembles the following code if the quoted string
parameters are equal. The strings must be quoted using double quotes.

.align is handled specially on certain targets. .align without any parameters
on ARM indicates a default alignment (4). Handle the special case in the target
parser, but fall back to the generic parser for the normal version.

The .ifne directive assembles the following section of code if the argument
expression is non-zero. Effectively, it is equivalent to if.

If the strings are not quoted, the first string stops at the first comma, and
the second string stops at the end of the line. Strings which contain
whitespace should be quoted. Unquoted space is to be discarded.

The .err directive produces an error whenever it is assembled. This can be
useful for preventing assembly when an unexpected condition occurs.

This adds support for the .short and its alias .hword for adding literal values
into the object file. This is similar to the .word directive, however, rather
than inserting a value of 4 bytes, adds a 2-byte value.

Offsets past the range of single-slash encoding are encoded as base64,
padded to 6 characters, and prefixed with two slashes. This encoding is
undocumented but used by MSVC.

Summary:
This removes the need to coerce UnknownABI to the default ABI (O32 for
MIPS32, N64 for MIPS64 [*]) in both MipsSubtarget and MipsAsmParser.
Clang has been updated to disable both possible default ABI's before enabling
the ABI it intends to use.
[*] N64 being the default for MIPS64 is not actually correct.
However N32 is not fully implemented/tested yet.

This enhances the macro parser to parse and handle parameter qualifications,
which is needed to support required formal parameters in macro definitions. A
required parameter may not be defaulted (though providing a default value is
accepted with a warning). This improves GAS compatibility.
Partially addresses PR9248.

ldrd r6, r7 [r2, #15]
simply gives an error and does not triggers an assertion.
As Jim points out, the diagnostic is really strange here,
but fixing that would be more complicated. The missing
comma results in the parser expecting a construct like r2[2],
which is the vector index thing the error message is talking
about. That's not what the user intended, though, and there's
nothing else in the instruction that looks at all like a vector.
Yet more fallout from not having a real parser here and trying
to do context-free generic matching for addressing modes.
