Reapply r66415, which was reverted in r66426 for

causing a bootstrap failure. Bootstraps here on
x86-32-linux and x86-64-linux. Requested by the
author Gabor Greif who says that a bug that might
have been causing the failure has since been fixed.

improve TLS support (see http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20090309/075220.html ), but that code is VERY brittle.
This patch just makes it a bit more resistant.

Match this pattern so that we can generate simpler code:

%a = ...
%b = and i32 %a, 2

%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.

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.
