    devel/boost-{all,libs}: Adjust range of OSVERSION to use LLVM from ports
    
    The reason to use LLVM from ports is that there is bug in Clang/LLVM
    of base system that causes assertion failure while building
    devel/boost-libs. The bug is already fixed with main, stable/14 and
    stable/13 branches of src repository. So we need to use LLVM from
    ports only with following ranges of OSVERSION.
    
    1. 1500000 <= OSVERSION < 1500017
    2. 1400000 <= OSVERSION < 1400509
    3. 1300000 <= OSVERSION < 1303502
    
    And commit 3b8c51bd37b0 adjusts the range as above.
    
    But there is a pitfall about it. The assertion failure happens only if
    base system is built with WITH_LLVM_ASSERTIONS variable set. By
    default it is set with main branch but not with stable/* and releng/*
    ones. So wheareas the failure happens with -CURRENT even if it is
    built with default variables settings, it doesn't happen with -STABLE
    and -RELEASE unless they are built with WITH_LLVM_ASSERTIONS set. IMHO
    majority of FreeBSD users use -RELEASE with official binary, and few
    -STABLE users set WITH_LLVM_ASSERTIONS. As a result adjustment with
    commit 3b8c51bd37b0 forces most -RELEASE and -STABLE users to build
    LLVM port unnecessarily.
    
    So adjust the range so LLVM from ports is used by default only if base
    system is -CURRENT with the assertion failure unfixed. And as a last
    resort for -STABLE and -RELEASE users who set WITH_LLVM_ASSERTIONS,
    add LLVM_FROM_PORTS option to devel/boost-libs that forces to use LLVM
    from ports.

+# Note about LLVM_FROM_PORTS option:
+# Build of this port fails with assertion failure of compiler due to
+# bug of LLVM/Clang in base system. The failure happens when all of
+# following conditions are satisfied.
+# * OSVERSION is included in either of following ranges.
+#   1. 1500000 <= OSVERSION < 1500017
+#   2. 1400000 <= OSVERSION < 1400509

+# By default WITH_LLVM_ASSERTIONS variable is set with -CURRENT but

+# the build failure, few -STABLE and -RELEASE user faces it.
+# Therefore by default this port uses LLVM from ports only if base
+# system is -CURRENT and OSVERSION is included in above ranges. It

+# -RELEASE built with WITH_LLVM_ASSERTIONS set, then he can't build
+# this port successfully on such system. So provide LLVM_FROM_PORTS
