Merge #1002 
1002: Update the LLVM pass list. r=nlewycky a=nlewycky

# Description
Adds optimizations of loops, and inlinling and some simple interprocedural optimization.

Measured on the libsodium benchmarks, the new pass pipeline is a 2.35% geomean improvement. No major performance regressions known.

3b2d751c55 Enable compilation for specific target 
By exposing the target information through `CompilerConfig`,
compiler(only LLVM at the moment) could create a machine with
different CPU feature flags other than current host, which makes it
capable to "cross compile" to some degree.

ebe8da7bd3 When accessing memory, use byte aligned accesses. 
LLVM's instcombine will attempt to bump the alignment when it can prove that it's safe to do so.

Fixes #969.

ef4b3c3428 Improve some TBAA label names, particular for memory. 
Memory can't change between static and dynamic, so use that in the TBAA label
name.

Distinguish between local and imported memory, table and globals.

edb6cbefca fix(runtime-core) Share the definition of Trampoline across all the backends. 
This patch updates all the backends to use the definition of
`Trampoline` as defined in the `wasmer_runtime_core::typed_func`
module. That way, there is no copy of that type, and as such, it is
easier to avoid regression (a simple `cargo check` does the job).

This patch also formats the `use` statements in the updated files.

Merge #901 
901: Set target triple and datalayout when creating the LLVM module. r=nlewycky a=nlewycky

We were giving LLVM a triple and datalayout only when producing native code from the LLVM IR. With this change, we tell LLVM as early as possible so that the entire optimization stack knows that it's safe to use target-specific constructs (including target intrinsics `@llvm.x86.sse2.ucomieq.sd`) as well as cost models (for autovectorization) and knowing the bitwidth of the registers so that we can know it's profitable to eliminate redundant extend/truncate casts.
