I discovered that Clang changes register types without any warning when processing invalid assembly code.
I believe Clang should more accurately verify assembly syntax.
```
.intel_syntax noprefix
Bug:
lar R11, R8W
movmskpd R9, XMM0
pmovmskb R10, MM2
tpause RDX
umwait RBP
```
```
Bug:
lar r11,r8
movmskpd r9d,xmm0
pmovmskb r10d,mm2
tpause edx
umwait ebp
```
