  1. [CHERI-RISC-V] Add baseline test for conflicting sanitizer library names 

    We currently attempt to link libclang_rt-<lib>-riscv{32,64}.a for both
purecap and non-purecap. Since there is no per-ABI subdirectory for the
compiler-rt libraries, we should be using a different basename for the
purecap runtime libs.

  2. [compiler-rt][cmake] Correctly set architecture for purecap 

    We have to use a different architecture suffix for purecap since not all
sanitizers are supported. We already have one for MIPS but the previous
logic to select it based on the target triple no longer works. This change
should be more future proof and sets the RISC-V architecture suffixes to
riscv{32,64}c.

  4. [sanitizer] Fix build on FreeBSD RISC-V 

    We have to avoid calling renameat2 and clone on FreeBSD.
Additionally, the mcontext structure has different members.

  9. [CHERI-RISC-V] Use suffixed sanitizer libraries for purecap 

    Since both the plain RISC-V and purecap RISC-V compiler-rt libraries will
be installed to the same directory we have to use a different name for
the purecap ones. This patch uses a "c" suffix for the purecap ones.
