Avoids malloc and is a lot denser. We lose iteration over target independent
attributes, but that's a strange interface anyways and didn't have any users
outside of AttrBuilder.

GNU as rejects them and there are configure scripts in the wild that check if
the assembler rejects ".align 3" to determine whether the alignment is in bytes
or powers of two.

It's completely unnecessary and can be replace with proper

Seems to be allot simpler, and also paves the
way for further improvements.
v2: rebased on master, use 0 in BUFFER_LOAD_FORMAT_XYZW,
use VGPR0 in dummy EXP, avoid compiler warning, break

v3: correctly use V_ADD_F32_e64

If the frame pointer is omitted, and any stack changes occur in the inline

With bundle alignment, instructions all get their own MCFragments
(unless they are in a bundle-locked group). For instructions with
fixups, this is an MCDataFragment. Emitting actual data (e.g. for
.long) attempts to re-use MCDataFragments, which we don't want int
this case since it leads to fragments which exceed the bundle size.
So, don't reuse them in this case.
Also adds a test and fixes some formatting.
