c6341e6e50 When promoting the vector elements in CopyToParts, use vector trunc 
instead of scalarizing, and doing an element-by-element truncat.

expressions, but Chris wants to instead reduce the set of possible constant
expression types.

448da519cc Fix PR10103: Less code for enum type translation. 
In cases such as the attached test, where the case value for a switch
destination is used in a phi node that follows the destination, it
might be better to replace that value with the condition value of the
switch, so that more blocks can be folded away with
TryToSimplifyUncondBranchFromEmptyBlock because there are less
conflicts in the phi node.

3ebb05d9a6 When scalar replacement returns a vector type, only accept it if the vector 
type's bitwidth matches the (allocated) size of the alloca. This severely
pessimizes vector scalar replacement when the only vector type being used is
something like <3 x float> on x86 or ARM whose allocated size matches a
<4 x float>.

I hope to fix some of the flawed assumptions about allocated size throughout
scalar replacement and reenable this in most cases.

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.

54c47c1ce9 Remove MethodProtos/MethodBodies and allocation_order_begin/end. 
Targets that need to change the default allocation order should use the
AltOrders mechanism instead. See the X86 and ARM targets for examples.

The allocation_order_begin() and allocation_order_end() methods have been
replaced with getRawAllocationOrder(), and there is further support
functions in RegisterClassInfo.

It is no longer possible to insert arbitrary code into generated
register classes. This is a feature.

b4c704877d Provide AltOrders for specifying alternative allocation orders. 
A register class can define AltOrders and AltOrderSelect instead of
defining method protos and bodies. The AltOrders lists can be defined
with set operations, and TableGen can verify that the alternative
allocation orders only contain valid registers.

This is currently an opt-in feature, and it is still possible to
override allocation_order_begin/end. That will not be true for long.
