cpu_asm.c: Compile shorter code blocks for GBA RAM lines. Also stop keeping track of branches internal to the blocks, ending them at the first unconditional branch.
arm_guru_meditation.c: Allow the recoverable error screens to be dismissed by pressing a key.
cpu_asm.c: Fix adding the BIOS (address 8) into the branch target array.
cpu_asm.c: Eliminate 4 KiB of global variables, putting them on the stack and reducing memory copying in order to determine the set of branches leading away from the current block.
Merge branch 'master' into basic-blocks
