cf89c1934c riscv32: align stack pointer to 16-bytes 
Even though rv32 is only 32-bits, all RISC-V stacks must be aligned to a
16-byte boundary. For discussion on this, see:

https://github.com/riscv-non-isa/riscv-elf-psabi-doc/issues/21

As an example of why this is important, the `c.addi16sp` compressed
instruction is only able to adjust the stack pointer by 16-byte
increments.

2f9e374431 find_fde: make text_base optional 
No platforms currently use relative addressing. Make this parameter
optional in order to support targets where this value is not available.

1b30c6a79d cargo: support building as part of libstd 
Support using `unwinding` as a backend for the libstd `unwind` crate.
This will enable unwinding support for new targets while allowing us to
continue to use `libunwind` from llvm for supported targets.
