[PPCAsmPrinter] support 'L' output template for memory operands
Summary:
L is meant to support the second word used by 32b calling conventions for 64b arguments.
This is required for build 32b PowerPC Linux kernels after upstream
commit 334710b1496a ("powerpc/uaccess: Implement unsafe_put_user() using 'asm goto'")
Thanks for the report from @nathanchance, and reference to GCC's
implementation from @segher.
