Subject: [PATCH] Do not split decimal float suffix from constant
N1312 draft of ISO/IEC WDTR24732 defines additional floating types
with given suffixes:
_Decimal32 DF, df
_Decimal64 DD, dd
_Decimal128 DL, dl
These suffixes must stick on numeric part of the constant as classic
float or long float does.
