some test cases can't pass in ARM, but in X86_64 is OK.

OS: centos 7.6
ARCH: aarch64(ARM)

LuaJIT compile command:

make TARGET_STRIP=@: CCDEBUG=-g CC=cc XCFLAGS="-DLUA_USE_APICHECK -DLUA_USE_ASSERT -DLUAJIT_NUMMODE=2 -g -O1 -std=gnu99"

only two cases occurs exception:

=== test/ffi/ffi_jit_struct.lua
/DATA/yfli1/test/upngx-test/luajit-test-suite/luajit/bin/luajit-2.1.0-beta3: bad light userdata pointer
stack traceback:

Failed test when running /DATA/yfli1/test/upngx-test/luajit-test-suite/luajit/bin/luajit-2.1.0-beta3 catch_cpp.lua 1: 256

=== test/misc/catch_wrap.lua
/DATA/yfli1/test/upngx-test/luajit-test-suite/luajit/bin/luajit-2.1.0-beta3: bad light userdata pointer
stack traceback:

Reproduce the reported failures using the given LuaJIT build command on aarch64: test/ffi/ffi_jit_struct.lua and test/misc/catch_wrap.lua both report "bad light userdata pointer." Compare these cases with an x86_64 run and inspect the referenced test scripts and their stack traces. Done means both ARM cases pass without the exception.
