Separate compilation and linker phases (#376)

Separate between compilation and linker phases to allow deploy time linking and back-porting era compiler changes to fix #91. Unlinked contract binaries (caused by missing libraries or missing factory dependencies in turn) are emitted as raw ELF object. Few drive by fixes: - #98 - A compiler panic on missing libraries definitions. - Fixes some incosistent type forwarding in JSON output (empty string vs. null object). - Remove the unused fallback for size optimization setting. - Remove the broken `--lvm-ir` mode. - CI workflow fixes. --------- Signed-off-by: Cyrill Leutwiler <bigcyrill@hotmail.com> Signed-off-by: xermicus <bigcyrill@hotmail.com> Signed-off-by: xermicus <cyrill@parity.io>
