Internal Error in build process on Windows

Hi all,

I use Visual Studio 2022 (17.0.4) on WSL 1 Ubuntu to build OpenJDK for 
Windows on Windows 11.
I sometimes saw Internal Error in masm as following:

```
  Assembling: 
c:\github-forked\jdk\src\jdk.incubator.vector\windows\native\libjsvml\jsvml_d_cos_windows_x86.S

MASM : fatal error A1016: Internal error
```

I saw same errors in other asm files in jdk.incubator.vector .
I can finish build normally when I run `make` some times.
I guess it is a problem in masm, but I haven't found out the condition 
to reproduce, so I've not yet reported this problem to Microsoft 
community.

Have you ever seen similar errors? Please share if you know how to avoid 
this.


Thanks,

Yasumasa
