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: 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: Fix VLD of single element to all lanes

Fix several bugs in VLD of single element to all lanes:

The "single element to all lanes" form of VLD1 differs from those for
VLD2, VLD3 and VLD4 in that bit 5 indicates whether the loaded element
should be written to one or two Dregs (rather than being a register...

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...

target-arm: use make_float32() to make constant floats for VRSQRTS

The preferred way to create a constant floating point value is to use
make_float32() rather than doing a runtime int32_to_float32().
Convert the code in the VRSQRTS helper to work this way....

target-arm: Fix VRECPS edge cases handling

Correct the handling of edge cases for the VRECPS instruction: * this is a Neon instruction so uses the "standard FPSCR value" * (zero, inf) is a special case which returns 2.0

target-arm: Set Q bit for overflow in SMUAD and SMLAD

SMUAD and SMLAD are supposed to set the Q bit if the addition of
the two 16x16 multiply products and optional accumulator overflows
considered as a signed value. However we were only doing this check
for the addition of the accumulator, not when adding the products,...

target-arm: Fix GE bits for v6media signed modulo arithmetic

Fix the signed modulo arithmetic helpers for the v6media
instructions (SADD8, SSUB8, SADD16, SSUB16, SASX, SSAX) to set
the GE bits correctly (based on the result of the add or subtract
before it is truncated to 16 bits, not after)....
