[AFDO] Merge function attributes after inlining

This patch teaches the sample profile loader to merge function
attributes after inlining functions.

Without this patch, the compiler could inline a function requiring the
512-bit vector width into its caller without merging function
attributes, triggering a failure during instruction selection.
