Michael Munday 55ac5b50b0 cmd/compile: fix large global variables in -linkshared mode on s390x ... When rewriting loads and stores accessing global variables to use the GOT we were making use of REGTMP (R10). Unfortunately loads and stores with large offsets (larger than 20-bits) were also using REGTMP, causing it to be clobbered and subsequently a segmentation fault. This can be fixed by using REGTMP2 (R11) for the rewrite. This is fine because REGTMP2 only has a couple of uses in the assembler (division, high multiplication and storage-to-storage instructions). We didn't use REGTMP2 originally because it used to be used more frequently, in particular for stores of constants to memory. However we have now eliminated those uses. This was found while writing a test case for CL 63030. That test case is included in this CL.
