Otherwise, if TARGET_CONST16 or TARGET_AUTOLITPOOLS is enabled, DI/SF/DFmode
constant assignments will not benefit from their splitting or constantsynth.
gcc/ChangeLog:
* config/xtensa/xtensa.cc (do_largeconst):
Change split_DI_SF_DF_const() to be called unconditionally.

In Xtensa ISA, when TARGET_CONST16 is not enabled, such large immediate
