target-arm: Set softfloat cumulative exc flags from correct FPSCR bits

When handling a write to the ARM FPSCR, set the softfloat cumulative
exception flags from the cumulative flags in the FPSCR, not the
exception-enable bits. Also don't apply a mask: vfp_exceptbits_to_host...

target-arm: wire up the softfloat flush_input_to_zero flag

Wire up the new softfloat support for flushing input denormals
to zero on ARM. The FPSCR FZ bit enables flush-to-zero for
both inputs and outputs, but the reporting of when inputs are
flushed to zero is via a separate IDC bit rather than the UFC...

target-arm: fix SMMLA/SMMLS instructions

SMMLA and SMMLS are broken on both in normal and thumb mode, that is
both (different) implementations are wrong. They try to avoid a 64-bit
add for the rounding, which is not trivial if you want to support both
SMMLA and SMMLS with the same code....

target-arm: fix UMAAL instruction

UMAAL should use unsigned multiply instead of signed.

This patch fixes this issue by handling UMAAL separately from
UMULL/UMLAL/SMULL/SMLAL as these instructions are different
enough. It also explicitly list instructions in case and catch...

target-arm: Correct result in saturating cases for VQSHL of s8/16/32

Where VQSHL of a signed 8/16/32 bit value saturated, the result
value was not being calculated correctly (it should be either
the minimum or maximum value for the size of the signed type)....

target-arm: Fix VQSHL of signed 64 bit values by shift counts >= 64

VQSHL of a signed 64 bit non-zero value by a shift count >= 64 should
saturate; return the correct value in this case.
