* Add support for R_ARM_THM_MOVW_ABS_NC/THM_MOVT_ABS
These are sometimes emitted by the Rust LLVM compiler.

* Discard LLVM bitcode from extension applications
LLVM-based compilers may include uncompressed bitcode in object files
to help with link-time optimization. However this can bloat binary sizes
from KB to MB.
* Expose alligned_malloc/free functions to applications
This is required to implement a global allocator in Rust.
