Check for the presence of a CPU feature at runtime.

When the feature is known to be enabled at compile time (e.g. via -Ctarget-feature) the macro expands to true.

Supported arguments are:

• "32s"
• "f"
• "d"
• "frecipe"
• "div32"
• "lsx"
• "lasx"
• "lam-bh"
• "lamcas"
• "ld-seq-sa"
• "scq"
• "lbt"
• "lvz"
• "ual"
