That is, the conversion rules are as: (common_type) c2 == (common_type) (uint32_t) (is_unsigned ? (uint32_t)c2 : (uint32_t)(int32_t)c2) In the signed case we lose the desired sign extensions because of the argument promotion rules of the ternary operator. Solve the problem by doing the round-trip parsing through the intermediate type and back to the desired common type (all at one expression).

So far only "tcg/tcg.h" requires these headers. Remove the "target-tcg.h" header dependency on TCG frontends, so we don't have to rebuild all frontends when hacking a single backend.

Start by moving tcg_initialize(). The new CPUClass.tcg_opts field may eventually become a pointer, but keep it an embedded struct for now, to make code conversion easier.

In the case of ARM, that includes: 1) the vcpu thread got a SIGBUS indicating a memory error, and we need to deliver a Synchronous External Abort to the guest to let it know about the error. 2) the kernel told us about a debug exception (breakpoint, watchpoint) but it is not for one of QEMU's own gdbstub breakpoints/watchpoints so it must be a breakpoint the guest itself has set up, therefore we need to deliver it to the guest. So in order to reuse code, the same arm_do_interrupt function is used. This is all fine, but we need to avoid calling it using the callback registered in CPUClass, since that one is now TCG-only. Fortunately this is easily solved by replacing calls to CPUClass::do_interrupt() with explicit calls to arm_do_interrupt().

Therefore, what we can do safely to restrict the TCG fields to TCG-only builds, is to move all tcg cpu operations into a separate header file, which is only included by TCG, target-specific code. This leaves just a NULL pointer in the cpu.h for the non-TCG builds. This also tidies up the code in all targets a bit, having all TCG cpu operations neatly contained by a dedicated data struct.
