linux-user/flatload: fix initial stack pointer alignment
Stack pointer alignment code incorrectly adds stack_size to sp instead
of subtracting it. It also does not take flat_argvp_envp_on_stack() into
account when calculating stack_size. This results in initial stack
pointer misalignment with certain set of command line arguments and
environment variables and correct alignment for the same binary with a
different set of arguments. This misalignment causes failures in the
following tests in the testsuite of gcc built for xtensa uclinux:
gcc.dg/torture/vshuf-v64qi.c
gcc.dg/torture/vshuf-v8sf.c
gcc.dg/torture/vshuf-v8si.c
