8b4b874cc6 Match this pattern so that we can generate simpler code: 
%a = ...
  %b = and i32 %a, 2
  %c = srl i32 %b, 1
  %d = br i32 %c, 

into

  %a = ...
  %b = and %a, 2
  %c = X86ISD::CMP %b, 0
  %d = X86ISD::BRCOND %c ...

This applies only when the AND constant value has one bit set and the SRL
constant is equal to the log2 of the AND constant. The back-end is smart enough
to convert the result into a TEST/JMP sequence.

54f302272c Modify getRegisterValueType() to allow for a register being in mutliple 
register classes. Before, MVT::Other would be returned anytime a reg was
in multiple register classes. Now, MVT::Other is only returned if the types
for those register classes differ.

beaec4cbf6 When optimizing with debug info, don't keep the 
stoppoint nodes around until Legalize; doing this
imposed an ordering on a sequence of loads that
came from different lines, interfering with scheduling.

ad9ad7c827 Fix a bug in our autoupgrade support: in an argument list to a function 
call, we should treat "i64 zext" as the start of a constant expr, but
"i64 0 zext" as an argument with an obsolete attribute on it (this form
is already tested by test/Assembler/2007-07-30-AutoUpgradeZextSext.ll).

Make the autoupgrade logic more discerning to avoid treating "i64 zext"
as an old-style attribute, causing us to reject a valid constant expr.
This fixes PR3876.

4f9797d683 two changes: 
1. Make instcombine always canonicalize trunc x to i1 into an icmp(x&1).  This 
   exposes the AND to other instcombine xforms and is more of what the code
   generator expects.
2. Rewrite the remaining trunc pattern match to use 'match', which 
   simplifies it a lot.
