Improve ResolveFunctions to:
...
a) use better local variable names (OldMT -> OldFT) where "M" is used to
mean "Function" (perhaps it was previously "Method"?)
b) print out the module identifier in a warning message so that it is
possible to track down in which module the error occurred.

At top of generated isel SelectCode() is this:
...
if (!N.Val->hasOneUse()) {
std::map<SDOperand, SDOperand>::iterator CGMI = CodeGenMap.find(N);
if (CGMI != CodeGenMap.end()) return CGMI->second;
}
Suppose a DAG like this:
X
^ ^
/ \
USE1 USE2
Suppose USE1 is being selected first and during which X is selected and
returned a new node. After this, USE1 is no longer an use of X. During USE2
selection, X will be selected again since it has only one use!
The fix is to always query CodeGenMap.

For ISD::RET, if # of operands >= 2, try selection the real data dep. operand
...
first before the chain.
e.g.
int X;
int foo(int x)
{
x += X + 37;
return x;
}
If chain operand is selected first, we would generate:
movl X, %eax
movl 4(%esp), %ecx
leal 37(%ecx,%eax), %eax
rather than
movl $37, %eax
addl 4(%esp), %eax
addl X, %eax
which does not require %ecx. (Due to ADD32rm not matching.)

Implement a little hack for parity with GCC on crafty. This speeds up
...
186.crafty by about 16% (from 15.109s to 13.045s) on my system.
This turns allocas with unions/casts into scalars. For example crafty has
something like this:
union doub {
unsigned short i[4];
long long d;
};
int f(long long a) {
return ((union doub){.d=a}).i[1];
}
Instead of generating loads and stores to an alloca, we now promote the
whole thing to a scalar long value.
This implements: Transforms/ScalarRepl/AggregatePromote.ll
