This fixes the few places where explicit checks for NOP_EXPR or CONVERT_EXPRs crept in.
A noticable change may be the tree-eh.c one where we previously
considered FP NOP_EXPRs trapping if flag_trapping_math
("Any fp arithmetic may trap") but now like FP CONVERT_EXPRs
only when honor_nans (but for some reason the honor_nans
cases don't check flag_trapping_math). I'm not 100% sure which
variant is more correct (this is FP <-> FP conversions thus
widenings, truncations, converts from/to DFP).
Bootstrap and regtest running on x86_64-unknown-linux-gnu.
