clover/llvm: Work around MSVC quirks

Two things:
1. While instantiating a template where clover::llvm and ::llvm are
   both resolvable for unscoped llvm, MSVC complains about ambiguity.
   Resolve by not using namespace clover, leaving only ::llvm as a
   valid namespace.
2. LLVM headers (specifically Allocator.h) use __declspec(restrict),
   but Mesa's util headers #define restrict to __restrict for C++.
   Since __declspec(__restrict) is invalid, make sure we always include
   Allocator.h first before the util header.
3. Change a uint/int to uint64_t to match the type returned from LLVM.
