Using llvm-mc built from r141535, all of the cases listed in this bug report
work, except the vcomisd tests shown in comment 7:

$ echo '0xc4 0xc1 0x7b 0x2f 0xc1'| ./llvm-mc -disassemble -triple="x86_64"
<stdin>:1:1: warning: invalid instruction encoding
0xc4 0xc1 0x7b 0x2f 0xc1
^
<stdin>:1:21: warning: invalid instruction encoding
0xc4 0xc1 0x7b 0x2f 0xc1

$ echo '0xc5 0xfb 0x2f 0xc1'| ./llvm-mc -disassemble -triple="x86_64"
<stdin>:1:1: warning: invalid instruction encoding
0xc5 0xfb 0x2f 0xc1
^
<stdin>:1:16: warning: invalid instruction encoding
0xc5 0xfb 0x2f 0xc1
               ^
