Since sibcall never returns, we can only use call-clobbered register as
GOT base. Otherwise, callee-saved register used as GOT base won't be
properly restored. sibcall_memory_operand is changed to allow 32-bit
GOT slot only with pseudo register as GOT base for RTL expansion. 2
new patterns, *sibcall_GOT_32 and *sibcall_value_GOT_32, are added to
expose GOT base register to register allocator so that call-clobbered
register will be used for GOT base.

This series of patches fix PR61441. This patch avoids various transformations

An unintended effect of the recently introduced machinery to handle
dynamic data member offsets in variable-length records (when
-fgnat-encodings=minimal) prevented GCC from describing correctly
inheritance information for classes in C++, which is a regression.
This change rectifies this machinery in this case.

disable dynamic data member offsets descriptions for TREE_BINFO

This series of patches fix PR61441. This patch makes resulting NaN values
