  linux-user: fix mips 32-on-64 prealloc case

MIPS only supports 31 bits of virtual address space for user space, so let's
make sure we stay within that limit with our preallocated memory block.

This fixes the MIPS user space targets when executed without command line
option.

  target-mips: Allow DSP access to be disabled once enabled.

Clear the DSP hflags at the start of compute_hflags.  Otherwise access
is not properly disabled once enabled.

  Log Message:
  -----------
  target-mips: Replace macros by inline functions

The macros RESTORE_ROUNDING_MODE and RESTORE_FLUSH_MODE silently used
variable env from their callers. Using inline functions with env passed
as a function argument is more transparent.

This modification was proposed by Peter Maydell.

  Log Message:
  -----------
  target-mips: Fix helper and tests for dot/cross-dot product instructions

Helper function for dpa_w_ph, dpax_w_ph, dps_w_ph and dpsx_w_ph incorrectly
defines halfword vector elements as unsigned values. This results in wrong
output which is not triggered in the tests as they also follow this logic.
