tcg-i386: Use QEMU_BUILD_BUG_ON instead of assert for frame size

We can check the condition at compile time, rather than run time.

tcg-arm: Implement tcg_register_jit

Allows unwinding past the code_gen_buffer.

tcg: Fix high_pc fields in .debug_info

I don't think the debugger actually looks at this for anything,
using the correct .debug_frame contents, but might as well get
it all correct.

tcg: Move the CIE and FDE header definitions to common code

These will necessarily be the same layout for all hosts. This limits
the amount of boilerplate required to implement jit debug for a host.

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: Allow non-constant control macros

This allows TCG_TARGET_HAS_* to be a variable rather than a constant,
which allows easier support for differing ISA levels for the host.

tcg: Simplify logic using TCG_OPF_NOT_PRESENT

Expand the definition of "not present" to include "should not be present".
This means we can simplify the logic surrounding the generic tcg opcodes
for which the host backend ought not be providing definitions....

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.
