Fix comment typos

While investigating PR c++/99538 I noticed two comment typos: "delared"
and "paramter". The first has a single occurrence, but the second a few
more. This patch fixes all of them.

gcc/ChangeLog:

	* config/i386/x86-tune-sched.cc (ix86_fuse_mov_alu_p): Fix
	comment typo, paramter -> parameter.
	* config/lm32/lm32.cc (lm32_std_gimplify_va_arg_expr): Likewise.

gcc/cp/ChangeLog:

	* cp-tree.h (processing_contract_condition): Fix comment typo,
	paramter -> parameter.
	* parser.cc (cp_parser_requires_expression): Fix comment typo,
	delared -> declared.

gcc/rust/ChangeLog:

	* rust-diagnostics.h (RUST_ATTRIBUTE_GCC_DIAG): Fix comment
	typo, paramter -> parameter.

gcc/testsuite/ChangeLog:

	* gcc.target/powerpc/ppc64-abi-1.c: Fix comment typos, paramter
	-> parameter.
	* gcc.target/powerpc/ppc64-abi-2.c: Likewise.
