Subject: [PATCH 008/188] LoongArch: Delete macro definition
 ASM_OUTPUT_ALIGN_WITH_NOP.

There are two reasons for removing this macro definition:
1. The default in the assembler is to use the nop instruction for filling.
2. For assembly directives: .align [abs-expr[, abs-expr[, abs-expr]]]
   The third expression it is the maximum number of bytes that should be
   skipped by this alignment directive.
   Therefore, it will affect the display of the specified alignment rules
   and affect the operating efficiency.

This modification relies on binutils commit 1fb3cdd87ec61715a5684925fb6d6a6cf53bb97c.
(Since the assembler will add nop based on the .align information when doing relax,
it will cause the conditional branch to go out of bounds during the assembly process.
This submission of binutils solves this problem.)

gcc/ChangeLog:

* config/loongarch/loongarch.h (ASM_OUTPUT_ALIGN_WITH_NOP):
	Delete.
