[Bug gas/10168] New: Wrong machine code for Thumb2 instruction PKHTB

[anthony dot fox at cl dot cam dot ac dot uk]

The ARM Thumb2 pseudo-instruction

PKHTB<c> <Rd>,<Rm>,<Rn>

should be assembled through

PKHBT<c> <Rd>,<Rm>,<Rn>

but is instead assembled through

PKHBT<c> <Rd>,<Rn>,<Rm>

For example:

$ echo ".code 16 pkhtb r1,r2,r3" | arm-elf-as -aln -EB -o /dev/null
   1 0000 EAC20103      .code 16 pkhtb r1,r2,r3

$ echo ".code 16 pkhbt r1,r2,r3" | arm-elf-as -aln -EB -o /dev/null
   1 0000 EAC20103      .code 16 pkhbt r1,r2,r3
