    aarch64: Add vector floating point extend pattern [PR113880, PR113869]

    This patch adds vector floating point extend pattern for V2SF->V2DF and
    V4HF->V4SF conversions by renaming the existing
aarch64_float_extend_lo_<Vwide>
    pattern to the standard optab one, i.e., extend<mode><Vwide>2. This allows
the
    vectorizer to vectorize certain floating point widening operations for the
    aarch64 target.

    gcc/ChangeLog:

            * config/aarch64/aarch64-builtins.cc (VAR1): Remap float_extend_lo_
            builtin codes to standard optab ones.
            * config/aarch64/aarch64-simd.md (aarch64_float_extend_lo_<Vwide>):
Rename
            to...
            (extend<mode><Vwide>2): ... This.

    gcc/testsuite/ChangeLog:

            * gcc.target/aarch64/extend-vec.c: New test.
