2018-02-09Clean up includesMarkus Armbruster
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes, with the change to target/s390x/gen-features.c manually reverted, and blank lines around deletions collapsed.

2017-12-18target/xtensa: import libisa sourceMax Filippov
The canonical way of dealing with Xtensa instructions decoding and encoding is through the libisa. Libisa is a configuration-independent library with a stable interface plus generated configuration-specific xtensa-modules.c file with implementations of decoding and encoding functions. Libisa is MIT-licensed and originally disributed xtensa-modules.c files are also MIT-licensed and are available as a part of xtensa configuration overlay.
