C++. This logic is required to trigger implicit instantiation of
function templates and member functions of class templates, which will
be implemented separately.

This commit includes support for -Wunused-parameter, printing warnings
for named parameters that are not used within a function/Objective-C
method/block. Fixes <rdar://problem/6505209>.

so that it can access the TargetData member (when available) and
use ValueTracking.h information to compute information for
SCEVUnknown Values.

Also add GetMinLeadingZeros and GetMinSignBits functions,
with minimal implementations.

gets involved, and we end up trying to recursively acquire a writer lock.  The fix for this is slightly horrible,
and involves passing a boolean "locked" parameter around in Constants.cpp, but it's better than having locked and
unlocked versions of most of the code.

addrec outside of a loop, this causes the addrec to be evaluated as
a linear addrec.

preferring to use their replacements in GRState. This further unifies the code
paths for such logic and leads to some code reduction.

well with the existing loadpre that j-t does to open up many new jump
threads earlier.

is implied by -Wall.  Group -Wno-unused-parameter

two that turns on -Wunused-parameter.
