This new syntax is built around putting each instruction on its own line
in a "mnemonic op, op, op" like syntax. It also uses conventional data
section directives like ".byte" and so on rather than requiring everything
to be in hierarchical S-expression format. This is a more natural syntax
for a ".s" file format from the perspective of LLVM MC and related tools,
while remaining easy to translate into other forms as needed.

Things of note:
- Other linkage types aren't handled yet. We'll figure it out with dynamic linking.
- Special LLVM globals are either ignored, or error out for now.
- TLS isn't supported yet (WebAssembly will have threads later).
- There currently isn't a syntax for alignment, I left it in a comment so it's easy to hook up.
- Undef is convereted to whatever the type's appropriate null value is.
- assert versus report_fatal_error: follow what other AsmPrinters do, and assert only on what should have been caught elsewhere.
