Kristina Brooks	22db696549	[builtins] Fix c?zdi2 on sparc64/Linux and ignore riscv32 On sparc64/Linux, sparc64 isn't defined; the canonical way of checking for sparc64 is sparc && arch64, which also works on the BSDs and Solaris. Since this problem does not occur on 32-bit architectures, riscv32 can be ignored. This fixes and refines rL324593.

[builtins] Fix c?zdi2 on sparc64/Linux and ignore riscv32

On sparc64/Linux, sparc64 isn't defined; the canonical way of
checking for sparc64 is sparc && arch64, which also works on the
BSDs and Solaris. Since this problem does not occur on 32-bit
architectures, riscv32 can be ignored. This fixes and refines rL324593.

[builtins] Workaround for infinite recursion in c?zdi2

gcc resolves `__builtin_c?z` to `__c?zdi2` which leads to infinite
recursion. This problem has been observed for sparc64, mips64 and riscv.
Presumably this happens whenever an arch without dedicated bit counting
instructions is targeted. This patch provides a workaround.
