Subject: [PATCH 051/188] LoongArch: Remove duplicate definition of
 CLZ_DEFINED_VALUE_AT_ZERO.

In the r14-5547 commit, C[LT]Z_DEFINED_VALUE_AT_ZERO were defined at
the same time, but in fact, CLZ_DEFINED_VALUE_AT_ZERO has already been
defined, so remove the duplicate definition.

gcc/ChangeLog:

	* config/loongarch/loongarch.h (CTZ_DEFINED_VALUE_AT_ZERO): Add
	description.
	(CLZ_DEFINED_VALUE_AT_ZERO): Remove duplicate definition.
