0b8ee7364a Add bound checking to arm, arm64 and riscv64
Checked on:
- i386/x86_64 (linux/windows)
- arm/arm64 (rapberry pi)
- riscv64 (simulator)
Not tested for arm softfloat because raspberry pi does not support it.

Modifications:

Makefile:
  add arm-asm.c to arm64_FILES
  add riscv64-asm.c (new file) to riscv64_FILES

lib/Makefile:
  add fetch_and_add_arm.o(new file) to ARM_O
  add fetch_and_add_arm64.o(new file) to ARM64_O
  add fetch_and_add_riscv64.o(new file) to RISCV64_O
  add $(BCHECK_O) to OBJ-arm/OBJ-arm64/OBJ-riscv64

tcc.h:
  Enable CONFIG_TCC_BCHECK for arm32/arm64/riscv64
  Add arm-asm.c, riscv64-asm.c

tcctok.h:
  for arm use memmove4 instead of memcpy4
  for arm use memmove8 instead of memcpy8

tccgen.c:
  put_extern_sym2: for arm check memcpy/memmove/memset/memmove4/memmove8
                   only use alloca for i386/x86_64
  for arm use memmove4 instead of memcpy4
  for arm use memmove8 instead of memcpy8
  fix builtin_frame_address/builtin_return_address for arm/riscv64

tccrun.c:
  Add riscv64 support
  fix rt_getcontext/rt_get_caller_pc for arm

tests/Makefile:
  add $(BTESTS) for arm/arm64/riscv64

tests/tests2/Makefile:
  Use 85 only on i386/x86_64 because of asm code
  Use 113 only on i386/x86_64 because of DLL code
