Rename fma4 intrinsics to just fma since they are now used for both FMA4 and FMA3. Autoupgrade support coming in a separate commit.

Before:
test.cc:2:18: note: place parentheses around the == expression to silence this warning
  if (0 == flags & 0xdd)
                 ^
                   (   )

Now:
test.cc:2:18: note: place parentheses around the == expression to silence this warning
  if (0 == flags & 0xdd)
                 ^
      (         )

Use sse_load_f32/64 for scalar FMA3 intrinsic patterns instead of 128-bit loads to match instruction behavior.

so we can destroy it even if it was constructed with "DelayInitialization = true",
and we didn't end up calling Preprocessor::Initialize.

Apart from being slightly cheaper, this fixes a real bug that hits 32 bit
linux systems. When passing a file larger than 2G to be linked (which isn't
that uncommon with large projects such as WebKit), clang's driver checks
if the file exists but the file size doesn't fit in an off_t and stat(2)
fails with EOVERFLOW. Clang then says that the file doesn't exist instead
of passing it to the linker.

FYI, LLVM_ON_WIN32 is useless.

-mhard-float, and -mfloat-abi= to the new function getMipsFloatABI. That
simplifies reuse of this code.

- Fixed IntegersSubsetGeneric copy/assignment behaviour. 
- Fixed IntegersSubsetGeneric::getSize/getSingleValue methods.
- Fixed IntegersSubsetGeneric::verify method.

Also IntegersSubset.h and IntegersSubsetMapping.h headers was fixed.

IntRange converted from struct to class. So main change everywhere is replacement of ".Low/High" with ".getLow/getHigh()"

Small fix due to buildbot failures on mingw32. Fixed call of parent constructor for case when parent is template.

llvm-svn: 157881

IntegersSubsetGeneric, IntegersSubsetMapping: added IntTy template parameter, that allows use either APInt or IntItem. This change allows to write unittest for these classes.

This will make it easier to add inlining support to more expressions.

This is the first of a series of patches which make changes to the backend to
emit unaligned load/store instructions (lwl,lwr,swl,swr) during instruction
selection.

the MachineOperand type has a valid offset.
