Sanjay Patel 0de1a4bc2d [PartiallyInlineLibCalls][x86] add TTI hook to allow sqrt inlining to depend on arg rather than result 
This should fix PR31455:
https://bugs.llvm.org/show_bug.cgi?id=31455

Craig Topper 49687104d6 [PartialInlineLibCalls] Teach PartialInlineLibCalls to honor nobuiltin, properly check the function signature, and check TLI::has 
Summary:
We shouldn't do this transformation if the function is marked nobuitlin.

We were only checking that the return type is floating point, we really should be checking the argument types and argument count as well. This can be accomplished by using the other version of getLibFunc that takes the Function and not just the name.

We should also be checking TLI::has since sqrtf is a macro on Windows.

Fixes PR32559.

Peter Collingbourne e52646cd80 PartiallyInlineLibCalls: Check sqrt result type before transforming it. 
Some configure scripts declare this with the wrong prototype, which can lead
to an assertion failure.
