887: Get aggressive about running cargo check over all packages with all features. r=nlewycky a=nlewycky
Fixes the one issue uncovered. The capstone disassembling support in the LLVM backend was broken. Fixed by removing it. Instead, use the `--llvm-object-file` flag to get a finished object file to disassemble with any disassembler.

863: Rewrite Min/Max to handle all cases correctly. Fixes 545 spectest failures. r=nlewycky a=nlewycky
# Description
The llvm backend was not quite following the Wasm spec for {F32,F64,F32x4xF64x2}{Min,Max}. We used the `@llvm.minnum` and `@llvm.maxnum` intrinsics which don't handle the corner cases the same. When we tried to use `@llvm.minimum` and `@llvm.maximum` which do, we get an internal error from the x86 backend. I was hoping that crash would go away with the upgrade to LLVM 9, but it does not.
Reimplement these operations using plain LLVM instructions.

Use them to implement three features in the LLVM backend, getting a valid ELF object file, the post-optimization LLVM IR and the pre-optimization LLVM IR.
Presently they are also global to the backend which is not ideal.
