Add libgmp 6.2.0 to third_party
Don't build it yet. That will come in the next review.

+
+This directory contains mpn functions optimized for MIPS3. Example of
+processors that implement MIPS3 are R4000, R4400, R4600, R4700, and R8000.
+
+RELEVANT OPTIMIZATION ISSUES
+
+1. On the R4000 and R4400, branches, both the plain and the "likely" ones,
+ take 3 cycles to execute. (The fastest possible loop will take 4 cycles,
+ because of the delay insn.)
+
+ On the R4600, branches takes a single cycle
+
+ On the R8000, branches often take no noticeable cycles, as they are
+ executed in a separate function unit..
+
+2. The R4000 and R4400 have a load latency of 4 cycles.
+
+3. On the R4000 and R4400, multiplies take a data-dependent number of
+ cycles, contrary to the SGI documentation. There seem to be 3 or 4
+ possible latencies.
+
+4. The R1x000 processors can issue one floating-point operation, two integer
+ operations, and one memory operation per cycle. The FPU has very short
+ latencies, while the integer multiply unit is non-pipelined. We should
+ therefore write fp based mpn_Xmul_1.
+
+STATUS
+
+Good...
