dd94bde661 Remove this test as it is too hard to fix after the 
latest EH changes, and in any case it is hard to
imagine how the original bug could be reintroduced.

90064ed445 Now that we don't output cleanups by default, the action 
offset needs to be adjusted in this test.

8dc0b93151 If the source and destination pointers in an llvm.memmove are known

ff33241e16 call libc memcpy/memset if array size is bigger then threshold. 
Coping 100MB array (after a warmup) shows that glibc 2.6.1 implementation on
x86-64 (core 2) is 30% faster (from 0.270917s to 0.188079s)

ccb3611881 When x86 addresses matching exceeds its recursion limit, check to 
see if the base register is already occupied before assuming it can be
used. This fixes bogus code generation in the accompanying testcase.

7132e00de7 This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. 
This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

8932bff7fe Fix the alignment requirements of several unpck and shuf instructions. 
Generalize isPSHUFDMask and add a unary SHUFPD pattern so that SHUFPD's
memory operand alignment can be tested as well, with a fix to avoid
breaking MMX's use of isPSHUFDMask.

fa3eeeedc0 Mark the SSE and MMX load instructions that 
X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle
with the isReMaterializable flag so that it is given a chance to handle
them. Without hoisting constant-pool loads from loops this isn't very
visible, though it does keep CodeGen/X86/constant-pool-remat-0.ll from
making a copy of the constant pool on the stack.
