7aef99b677 ARM vldm and vstm VFP instructions can take a data type suffix.
It's ignored by the assembler when present, but is legal syntax. Other
instructions have something similar, but for some mnemonics it's
only sometimes not significant, so this quick check in the parser will
need refactored into something more robust soon-ish. This gets some
basics working in the meantime.

affc6cf9d2 llvm-build: Add --native-target and --enable-targets options, and add logic to
handle defining the "magic" target related components (like native,
nativecodegen, and engine).
 - We still require these components to be in the project (currently in
   lib/Target) so that we have a place to document them and hopefully make it
   more obvious that they are "magic".

a4e07270bc When materializing an i32, SExt vs ZExt doesn't matter when we're trying to fit
in a 16-bit immediate.  However, for the shorter non-legal types (i.e., i1, i8,
i16) we should not sign-extend.  This prevents us from materializing things
such as 'true' (i.e., i1 1).
