target-sh4: Split the LDST macro into 2 sub-macros

The LDST macro is used to generate ldc and stc instructions that work with a
specific register. However, the SGR register only supports stc up to SH4A,
which supports both stc and ldc. This patch creates two sub-macros named LD...

Replace assert(0) with abort() or cpu_abort()

Large page TLB flush

QEMU uses a fixed page size for the CPU TLB. If the guest uses large
pages then we effectively split these into multiple smaller pages, and
