Reid Kleckner ab99e24e94 X86: Fix conflict over ESI between base register and rep;movsl 
The new solution is to not use this lowering if there are any dynamic
allocas in the current function. We know up front if there are dynamic
allocas, but we don't know if we'll need to create stack temporaries
with large alignment during lowering. Conservatively assume that we will
need such temporaries.

Benjamin Kramer a7c40ef022 Canonicalize header guards into a common format. 
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

Chris Lattner 2510de2bea reimplement memcpy/memmove/memset lowering to use MachinePointerInfo 
instead of srcvalue/offset pairs.  This corrects SV info for mem 
operations whose size is > 32-bits.

Dan Gohman bb919dfb6b Implement a bunch more TargetSelectionDAGInfo infrastructure. 
Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.
