MIPS/GAS: Keep the ISA bit in the addend of branch relocations

Correct a problem with the ISA bit being stripped from the addend of
compressed branch relocations, affecting RELA targets.  It has been
there since microMIPS support has been added, with:

commit df58fc944dbc6d5efd8d3826241b64b6af22f447
Author: Richard Sandiford <rdsandiford@googlemail.com>
Date:   Sun Jul 24 14:20:15 2011 +0000

<https://sourceware.org/ml/binutils/2011-07/msg00198.html>, ("MIPS:
microMIPS ASE support") and R_MICROMIPS_PC7_S1, R_MICROMIPS_PC10_S1 and
R_MICROMIPS_PC16_S1 relocations originally affected, and the
R_MIPS16_PC16_S1 relocation recently added with commit c9775dde3277
("MIPS16: Add R_MIPS16_PC16_S1 branch relocation support") actually
triggering a linker error, due to its heightened processing strictness
level:

$ cat test.s
	.text
	.set	mips16
foo:
	b	bar

	.set	bar, 0x1235
	.align	4, 0
$ as -EB -n32 -o test.o test.s
$ objdump -dr test.o

test.o:     file format elf32-ntradbigmips

Disassembly of section .text:

00000000 <foo>:
   0:	f000 1000 	b	4 <foo+0x4>
			0: R_MIPS16_PC16_S1	*ABS*+0x1230
	...
$ ld -melf32btsmipn32 -Ttext 0 -e 0 -o test test.o
test.o: In function `foo':
(.text+0x0): Branch to a non-instruction-aligned address
$

This is because the ISA bit of the branch target does not match the ISA
bit of the referring branch, hardwired to 1 of course.

Retain the ISA bit then, so that the linker knows this is really MIPS16
code referred:

$ objdump -dr fixed.o

fixed.o:     file format elf32-ntradbigmips

Disassembly of section .text:

00000000 <foo>:
   0:	f000 1000 	b	4 <foo+0x4>
			0: R_MIPS16_PC16_S1	*ABS*+0x1231
	...
$ ld -melf32btsmipn32 -Ttext 0 -e 0 -o fixed fixed.o
$

Add a set of MIPS16 tests to cover the relevant cases, excluding linker
tests though which would overflow the in-place addend on REL targets and
use them as dump patterns for RELA targets only.
