[jdk11u-dev] RFR: 8279076: C2: Bad AD file when matching SqrtF with UseSSE=0

[Aleksey Shipilev]

Unclean backport to fix the x86_32 problem. It is not clean, because Panama is not in 11u, so context in `.ad` is different.

Additional testing:
 - [x] Linux x86_32 fails new test without the fix, passes with it
