982d7674ff target/loongarch: Define function loongarch_cpu_post_init as static
Function loongarch_cpu_post_init() is implemented and used in the
same file target/loongarch/cpu.c, it can be defined as static function.

This patch moves implementation about function loongarch_cpu_post_init()
before it is referenced. And it is only code movement, no function
change.

a859022cea linux-user: Move ppc uabi/asm/elf.h workaround to osdep.h
Move the workaround out of linux-user/elfload.c, so that
we don't have to replicate it in many places.  Place it
immediately after the include of <signal.h>, which draws
in the relevant symbols.

Note that ARCH_DLINFO is not defined by the kernel header,
and so there's no need to undef it either.

7adf9ebb0a semihosting: Initialize heap once per process
While semihosting isn't really thread aware, the current
implementation allocates space for the heap per-thread.

Remove the heap_base and heap_limit fields from TaskState.
Replace with static variables within do_common_semihosting.
