Use movw+movt in ARMFastISel::ARMMaterializeGV. This eliminates a lot of constant pool entries for -O0 builds of code with many global variable accesses. This speeds up -O0 codegen of consumer-typeset by 2x because the constant island pass no longer has to look at thousands of constant pool entries. <rdar://problem/10629774> llvm-svn: 147712
