tcg-arm: Implement tcg_register_jit

Allows unwinding past the code_gen_buffer.

tcg-arm: Use AT_PLATFORM to detect the host ISA

With this we can generate armv7 insns even when the OS compiles for a
lower common denominator. The macros are arranged so that when we do
compile for a given ISA, all of the runtime checks for that ISA are...

tcg-arm: Simplify logic in detecting the ARM ISA in use

GCC 4.8 defines a handy __ARM_ARCH symbol that we can use, which
will make us nicely forward compatible with ARMv8 AArch32.

tcg-arm: Rename use_armv5_instructions to use_armvt5_instructions

As it really controls the availability of a thumb interworking
instruction on armv5t.

tcg-arm: Make use of conditional availability of opcodes for divide

We can now detect and use divide instructions at runtime, rather than
having to restrict their availability to compile-time.

tcg: Split rem requirement from div requirement

There are several hosts with only a "div" insn. Remainder is computed
manually from the quotient and inputs. We can do this generically.

tcg: Remove redundant tcg_target_init checks

We've got a compile-time check for the condition in exec/cpu-defs.h.

tcg-arm: Use movi32 in exit_tb

Avoid the mini constant pool for armv7, and avoid replicating
the test for pre-v7.

tcg-arm: Fix 64-bit tlb load for pre-v6

Found by inspection, since the effect of the bug was simply to
send all memory ops through the slow path.
