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. Wall time to assemble
the same cc1plus.s:

A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION
to TC_CONS_FIX_NEW via static variables. That's OK, but not best
practice. tc-ppc.c goes further in implementing its own replacement
for cons(), because the generic one doesn't allow relocation modifiers
on constants. This patch fixes both of these warts.
