gas: Pass max_bytes to TC_FRAG_INIT ommit 3ae729d5a4f63740ed9a778960b17c2912b0bbdd Author: H.J. Lu <hjl.tools@gmail.com> Date: Wed Mar 7 04:18:45 2018 -0800 x86: Rewrite NOP generation for fill and alignment increased MAX_MEM_FOR_RS_ALIGN_CODE to 4095 which resulted in increase of assembler time and memory usage by 5 times for inputs with many .p2align directives, which is typical for LTO output. This patch passes max_bytes to TC_FRAG_INIT so that MAX_MEM_FOR_RS_ALIGN_CODE can be set as needed and tracked by backend it so that HANDLE_ALIGN can check the maximum alignment for each rs_align_code frag.
