Restore r31 setting in powerpc32 swapcontext.
Commit ffe8a9a8318e1db225b22da8bc067408494bac5c, "powerpc: Remove rt_sigreturn usage on context function", removed from powerpc32 swapcontext a setting of r31 that is relied upon in subsequent code. I'm not sure why this didn't produce test failures in Adhemerval's 32-bit testing; in my (soft-float) testing in preparation for 2.30 release, I see several context-related failures FAIL: stdlib/tst-makecontext2 FAIL: stdlib/tst-makecontext3 FAIL: stdlib/tst-setcontext FAIL: stdlib/tst-setcontext2 FAIL: stdlib/tst-setcontext4 FAIL: stdlib/tst-setcontext7 FAIL: stdlib/tst-setcontext9 FAIL: stdlib/tst-swapcontext1 that did not appear in 2.29 testing. This patch restores the removed register setting in question, and thus fixes those failures. Tested for powerpc (soft-float). * sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S (__CONTEXT_FUNC_NAME): Restore setting of r31.
