x86-64: Fix TLSDESC relaxation for x32

For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix
even if it isn't required.  Otherwise linker can’t safely perform
GDesc -> IE/LE optimization.  X32 TLSDESC sequences can be:

40 8d 05 00 00 00 00	rex lea	x@TLSDESC(%rip), %reg
...
67 ff 10		call	*x@TLSCALL(%eax)

or the same sequence as LP64:

48 8d 05 00 00 00 00	lea	foo@TLSDESC(%rip), %reg
...
ff 10			call	*foo@TLSCALL(%rax)

We need to support both sequences for x32.  For both GDesc -> IE/LE
transitions,

67 ff 10		call	*x@TLSCALL(%eax)

should relaxed to

0f 1f 00		nopl	(%rax)

For GDesc -> LE transition,

40 8d 05 00 00 00 00	rex lea	x@TLSDESC(%rip), %reg

should relaxed to

40 c7 c0 fc ff ff ff	rex movl $x@tpoff, %reg

For GDesc -> IE transition,

40 8d 05 00 00 00 00	rex lea	x@TLSDESC(%rip), %reg

should relaxed to

40 8b 05 00 00 00 00	rex movl x@gottpoff(%rip), %eax

bfd/

	PR ld/25416
	* elf64-x86-64.c (elf_x86_64_check_tls_transition): Support
	"rex leal x@tlsdesc(%rip), %reg" and "call *x@tlsdesc(%eax)" in
	X32 mode.
	(elf_x86_64_relocate_section): In x32 mode, for GDesc -> LE
	transition, relax "rex leal x@tlsdesc(%rip), %reg" to
	"rex movl $x@tpoff, %reg", for GDesc -> IE transition, relax
	"rex leal x@tlsdesc(%rip), %reg" to
	"rex movl x@gottpoff(%rip), %eax".  For both transitions, relax
	"call *(%eax)" to "nopl (%rax)".

gas/

	PR ld/25416
	* config/tc-i386.c (output_insn): Add a dummy REX_OPCODE prefix
	for lea with R_X86_64_GOTPC32_TLSDESC relocation when generating
