[Bug c/17297] [3.4/3.5 Regression] ICE with FP vector constructor containing qnan calculation

With 3.4 branch we do get an ICE so this is also a 3.4 regression.
: Search converges between 2004-06-01-3.4 (#8) and 2004-06-15-3.4 (#9).

input.c: In function `main':
input.c:7: internal compiler error: in immed_double_const, at emit-rtl.c:466
Please submit a full bug report,
with preprocessed source if appropriate.
See  for instructions.

So with -ftraping-math turned on, we get another date on the mainline:
: Search converges between 2004-02-01-trunk (#445) and 2004-03-01-trunk (#446).
And a different ICE:
input.c: In function `main':
input.c:13: internal compiler error: in subreg_hard_regno, at emit-rtl.c:955
Please submit a full bug report,
with preprocessed source if appropriate.
See  for instructions.

So this is still a regression.
