C/C++ code can declare an extern function, which will show up as an import in WebAssembly's output. It's expected that the linker will resolve these, and mark unresolved imports as call_import (I have a patch which does this in wasmate).

Summary:
This is a temporary hack until we get around to remapping the vreg
numbers to local numbers. Dead vregs cause bad numbering and make
consumers sad.
We could also just look at debug info an use named locals instead, but
vregs have to work properly anyways so there!

Summary:
Follow the same syntax as for the spec repo. Both have evolved slightly
independently and need to converge again.
This, along with wasmate changes, allows me to do the following:
echo "int add(int a, int b) { return a + b; }" > add.c
./out/bin/clang -O2 -S --target=wasm32-unknown-unknown add.c -o add.wack
./experimental/prototype-wasmate/wasmate.py add.wack > add.wast
./sexpr-wasm-prototype/out/sexpr-wasm add.wast -o add.wasm
./sexpr-wasm-prototype/third_party/v8-native-prototype/v8/v8/out/Release/d8 -e "print(WASM.instantiateModule(readbuffer('add.wasm'), {print:print}).add(42, 1337));"
As you'd expect, the d8 shell prints out the right value.

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.

This is a temporary assembly syntax that will likely evolve along with
broader upcoming syntax changes.

This pass implements a simple algorithm for conversion from CFG to
wasm's structured control flow. It doesn't yet handle multiple-entry
loops; that will be added in a future patch.
It also adds initial support for switch statements.

Summary: This handles all load/store operations that WebAssembly defines, and handles those necessary for C++ such as i1. I left a FIXME for outstanding features which aren't required for now.

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.

Do the same for .weak (not implemented for now, but may as well to it). Update comment string to two semicolons.

Previously WebAssembly's datalayout string had -v128:8:128. This had been an
attempt to declare a certain level of support for unaligned SIMD accesses.
However, clang makes its own determinations for SIMD alignment that are
independent of the datalayout string, so this wasn't actually meaningful.

Summary:
D11924 implemented part of the floating-point comparisons, this patch implements the rest:
* Tell ISelLowering that all booleans are either 0 or 1.
* Expand the eq/ne/lt/le/gt/ge floating-point comparisons to the canonical ones (similar to what Mips32r6InstrInfo.td does).
* Add tests for ord/uno.
* Add tests for ueq/one/ult/ule/ugt/uge.
* Fix existing comparison tests to remove the (res & 1) code, which setBooleanContents stops from generating.

Summary: I somehow forgot to add these when I added the basic floating-point opcodes. Also remove ceil/floor/trunc/nearestint for now, and add them only when properly tested.
