  1. [BOLT][RISCV] Recognize mapping syms with encoded ISA 

    RISC-V supports mapping syms for code that encode the exact ISA for
which the code is valid. They have the form `$x<ISA>` where `<ISA>` is
the textual encoding of an ISA specification.

BOLT currently doesn't recognize these mapping symbol causing many
binaries compiled with newer versions of GCC (which emits them) to not
be properly processed. This patch makes sure BOLT recognizes them as
code markers.

Note that LLVM does not emit these kinds of mapping symbols yet so the
test is based on a binary produced by GCC.
