Another Platform: Macintosh (PowerMac G5) 11.0-CURRENT FreeBSD. Block's "buildworld".

I had submitted a clang crash report in to FreeBSD for its system clang (3.7) in 11.0-CURRENT on powerpc64 (an old PowerMac G5 is my example), where it crashed during the attempt to "buildworld". (See https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205183 .) Roman Divacky reports that my submittal is an example of this 25802 issue.

The "Affects Only Me" status might need to change if others also see the crash. In my context it is reproducible.

this crashes llc

[llvmbot]

think the assert is just bogus. The assembly has

.long .Ltmp8-.Ltmp13 # Call between .Ltmp13 and .Ltmp8

And Ltmp8 is befor Ltmp13, which is fine.

I will try to reduce the testcase a bit more.

Fixed in r257412.
