主题: third_party_llvm-project 代码入仓申请：适配龙芯架构clang编译

黄慧进，你好：

我是诚迈科技鸿蒙社区共建的接口人张志成，我们对llvm支持龙芯架构编译进行了适配，龙芯那边希望我们把适配内容合入到OpenHarmony主干中。

此次修改llvm主要目的是在OpenHarmony上支持LoongArch架构进行clang编译，主要修改：

涉及的目录有：clang、compiler-rt、libcxx、libcxxabi、libunwind、lld、llvm、openmp、llvm-build

另外，还需要同步修改以下几个仓：

1. build仓，增加编译识别arch:loongarch64和target:loongarch64-linux-ohos

2. kernel_linux_patches仓，对kernel/linux/patches/linux-5.10/prebuilts/usr/include增加loongarch64架构相关头文件

3. third_party_musl仓，增加loongarch64架构相关代码

经对编译出来的llvm工具链进行测试：RK3568(ARM)、RK3588(AArch64)和LS2K1500(LoongArch64)三个平台编译出来的镜像版本均能在对应开发板正常运行。

因此申请代码合入社区。请帮忙看一下是否可以接纳；如果能合入，我们需要进行哪些操作，多谢。
