[Bug libstdc++/37470] New: parallel/base.h log2 conflicts with math.h

[paul dot isaacson at earthlink dot net]

Line 112 of parallel/base.h declares an inline function log2.  This name is in
conflict with any usage of math.h log2 and causes compilation errors for
programs using pmode and math.h.  Changing the calls from log2 to xlog2
throughout the subdir parallel/*.h files (base.h, losertree.h,
multiseq_selection.h and random_shuffle.h) resolves the conflict.
