386e29065d Three changes:
1. Remove a bunch of ifdef'd code.
2. When a block just contains an uncond branch, change all blocks branching
   to it to jump to the destination instead.
3. If branch analysis tells us some edges in the machinecfg are not actually
   possible, remove them.

#2 triggers a suprisingly large number of times.

12143054aa Add an experimental cross-jumping implementation.
This is currently disabled by default and limited in several ways, but does
have a positive effect.

c70ddad2b7 Partially in response to PR926: insert the newly created machine basic
blocks into the basic block list when lowering the switch inst. into a
binary tree of if-then statements. This allows the "visitSwitchCase" func
to allow for fall-through behavior.

Added workaround for linker bug with linkonce sections.

programs to be compiled, linked and run.
