Laurent Vivier	6001f7729e	tcg: workaround branch instruction overflow in tcg_out_qemu_ld/st ... ppc64 uses a BC instruction to call the tcg_out_qemu_ld/st slow path. BC instruction uses a relative address encoded on 14 bits. The slow path functions are added at the end of the generated instructions buffer, in the reverse order of the callers. So more we have slow path functions more the distance between the caller (BC) and the function increases. This patch changes the behavior to generate the functions in the same order of the callers.

Richard Henderson	659ef5cbb8	tcg: Rearrange ldst label tracking ... Dispense with TCGBackendData, as it has never been used for more than holding a single pointer. Use a define in the cpu/tcg-target.h to signal requirement for TCGLabelQemuLdst, so that we can drop the no-op tcg-be-null.h stubs. Rename tcg-be-ldst.h to tcg-ldst.inc.c.
