i386: Do not use explicit operands for MOVS instructions [PR120019]
Some assemblers do not support MOVS instructions with explicit operands.
Emit instruction with implicit operands, but prefix the instruction with a
segment override prefix if the memory operand refers to ADDR_SPACE_SEG_FS
or ADDR_SPACE_SEG_GS named address space.
PR target/120019

* config/i386/i386.cc (ix86_print_operand): Handle 'v' operand
modifier to emit segment override prefix.

to emit segment override prefix.
(*strmovsi_1): Ditto.
(*strmovhi_1): Ditto.
(*strmovqi_1): Ditto.
(*rep_movdi_rex64): Ditto.
(*rep_movsi): Ditto.
