[PATCH 0/4] RISC-V: Implement TLS Descriptors.

[Tatsuyuki Ishi]

This patchset implements TLS Descriptors (TLSDESC) for RISC-V targets, per
the specification draft at [1].

This patchset is based on top of [2].

No regression in binutils and gcc tests for rv64gc, tested alongside the
gcc and glibc implementation (will be posted shortly).
