8bd3e4d5a1 Replace {u,i}128_* lang items with __rust_{u,i}128_* unmangled functions 
The -Zlower-128bit-ops feature is completely broken, as libcore needs
those lang items to compile with this feature, but they are only
provided by compiler_builtins, which itself depends on libcore.
According to rust-lang/rust#58969 the feature never got finished.

This commit removes the associated lang items and replaces them with
normal unmangled functions, when there is no existing intrinsic. This
makes it easier for alternative codegen backends to implement 128bit
integer support.

f783ff454b Remove most #[inline] annotations 
These annotations fall into a few categories

* Some simply aren't needed since functions will always be in the same
  CGU anyway and are already candidates for inlining.
* Many are on massive functions which shouldn't be inlined across crates
  due to code size concerns.
* Others aren't necessary since calls to this crate are rarely inlined
  anyway (since it's lowered through LLVM).

If this crate is called directly and inlining is needed then LTO can
always be turned on, otherwise this will benefit downstream consumers by
avoiding re-codegen'ing so many functions.
