target-arm: Use global env in iwmmxt_helper.c helpers

Use the global 'env' variable in the helper functions in iwmmxt_helper.c.
This means we don't need to pass env as an argument to them any more.

target-arm: Make Neon helper routines use correct FP status

Make the Neon helper routines use the correct FP status from
the CPUEnv rather than using a dummy static one. This means
they will correctly handle denormals and NaNs and will set
FPSCR exception bits properly....

target-arm: Fix VCLE.F32 #0, VCLT.F32 #0 NaN handling

Implementing the floating-point versions of VCLE #0 and VCLT #0 by
doing a GT comparison and inverting the result gives the wrong
result if the input is a NaN. Implement as a GT comparison with the
operands swapped instead....

target-arm: Correct ABD's handling of negative zeroes

Implement ABD by taking the absolute value of the difference
of the operands (as the ARM ARM specifies) rather than by
flipping the order of the operands to the subtract based
on the results of a comparison. The latter approch gives...

target-arm: Use new softfloat min/max functions for VMAX, VMIN

Use the new softfloat min/max functions to implement the Neon VMAX
and VMIN instructions. This allows us to get the right behaviour
for NaN and negative zero.

target-arm/helper.c: For float-int conversion helpers pass ints as ints

Correct the argument and return types for the float<->int conversion helper
functions so that integer arguments and return values are declared as
uint32_t/uint64_t, not float32/float64. This allows us to remove the...

target-arm: Return right result for Neon comparison with NaNs

Fix the helper functions implementing the Neon floating point comparison
ops (VCGE, VCGT, VCEQ, VACGT, VACGE) to return the right answer when
one of the values being compared is a NaN.

target-arm/neon_helper.c: Use make_float32/float32_val macros

Use the softfloat make_float32 and float32_val macros to convert between
softfloat's float32 type and raw uint32_t types, rather than private
conversion functions.

target-arm: Don't leak TCG temp for UNDEFs in Neon load/store space

Move the allocation and freeing of the TCG temp used for the address for
Neon load/store instructions so that we don't allocate the temporary
until we've done enough decoding to know that the instruction is not...
