9568e5c3c3 Teach dag combine to match halfword byteswap patterns. 
1. (((x) & 0xFF00) >> 8) | (((x) & 0x00FF) << 8)
   => (bswap x) >> 16
2. ((x&0xff)<<8)|((x&0xff00)>>8)|((x&0xff000000)>>8)|((x&0x00ff0000)<<8))
   => (rotl (bswap x) 16)

This allows us to eliminate most of the def : Pat patterns for ARM rev16
revsh instructions. It catches many more cases for ARM and x86.

b85e4eba85 rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which is 
for pre-2.9 bitcode files.  We keep x86 unaligned loads, movnt, crc32, and the
target indep prefetch change.

As usual, updating the testsuite is a PITA.

3a3465b71d Add a new function attribute, nonlazybind, which inhibits lazy-loading 
optimizations when emitting calls to the function;  instead those calls may
use faster relocations which require the function to be immediately resolved
upon loading the dynamic object featuring the call.  This is useful when it
is known that the function will be called frequently and pervasively and
therefore there is no merit in delaying binding of the function.

Currently only implemented for x86-64, where it turns into a call through
the global offset table.

Patch by Dan Gohman, who assures me that he's going to add LangRef documentation
for this once it's committed.

c2492c28ef Add a testcase for checking the integer-promotion of many different vector 
types (with power of two types such as 8,16,32 .. 512).

only if the target of the conversion is an integer (when the type action is
scalarize).

Add handling to the legalization of vector load/store in cases where the saved
vector is integer-promoted.
