Akira Hatanaka b45b1ea86f [Inliner] Merge the attributes of the caller and callee functions
This patch turns off the fast-math optimization attribute on the caller
if the callee's fast-math attribute is not turned on.

For example,

- before inlining
 caller: "less-precise-fpmad"="true"
 callee: "less-precise-fpmad"="false"

- after inlining
 caller: "less-precise-fpmad"="false"

Alternatively, it's possible to block inlining if the caller's and
callee's attributes don't match. If this approach is preferable to the
one in this patch, we can discuss post-commit.

target-cpu and target-features attribute strings as the caller.

Evgeniy Stepanov 2ad3698b70 Disable inlining between sanitized and non-sanitized functions.
Inlining between functions with different values of sanitize_* attributes
leads to over- or under-sanitizing, which is always bad.
