On gen 8 and later devices, the GTT stolen memory size when GGMS equals
0 is 0 (no preallocated memory) rather than 1MB [1].

Convert all targets simultaneously, as the gen_intermediate_code
function disappears from the target. While there are possible
workarounds, they're larger than simply performing the conversion.

There are multiple special cases for this instruction.
(1) The saturate to normal maximum instead of overflow to infinity is
handled by the new float_round_nearest_even_max rounding mode.
(2) The 0 * n + c special case is handled by the new
float_muladd_suppress_add_product_zero flag.
(3) The Inf - Inf -> 0 special case can be detected after the fact
by examining float_flag_invalid_isi.

This instruction has a special case that 0 * x + c returns c
without the normal sign folding that comes with 0 + -0.
Use the new float_muladd_suppress_add_product_zero to
describe this.

There are no special cases for this instruction. Since hexagon
always uses default-nan mode, explicitly negating the first
input is unnecessary. Use float_muladd_negate_product instead.
