Also, fixed static case in presence of eax livin. This fixes PR331
PS: Why don't we still have push/pop instructions? :)

field into SubclassData in Value. This shrinks GlobalVAlue from 48->40
bytes, Function from 88->76, and GlobalVariable from 76->68. This trims
4640 bytes off my testcase, reading a bc file without materializing any
functions.

object is always constant. As such, evaluate it at compile time instead of storing
it as an ivar in SymbolTableListTraits. This shrinks every SymbolTableListTraits
ilist by a word, shrinking BasicBlock from 44->40 bytes, Function from 96->88 bytes,
and Module from 60->52 bytes.

of two. This shrinkifies Function by 8 bytes (104->96) and Module by 8
bytes (68->60). On a testcase of mine, this reduces the memory used to
read a module header from 565680b to 561024, a little over 4K.

replaced it with a FIXME should have determined what did work. Then he would have
realized that the code was in fact correct, and would have avoided breaking it.

Subtarget option names must be given in lower case in order to be
recognized. Fixes test/CodeGen/Alpha/ctlz.ll

Use the new parameter on Function::getIntrinsicID to identify cases where
a function is being called with an "llvm." name but it isn't actually an
intrinsic. In such cases generate an error.

Don't assert everytime an intrinsic name isn't recognized. Instead, make
the assert optional when callin getIntrinsicID(). This allows the assembler
to handle invalid intrinsic names gracefully.

This sinks the two stores in this example into a single store in cond_next. In this
case, it allows elimination of the load as well:
store double 0.000000e+00, double* @s.3060
%tmp3 = fcmp ogt double %tmp1, 5.000000e-01 ; <i1> [#uses=1]
br i1 %tmp3, label %cond_true, label %cond_next
cond_true: ; preds = %entry
store double 1.000000e+00, double* @s.3060
br label %cond_next
cond_next: ; preds = %entry, %cond_true
%tmp6 = load double* @s.3060 ; <double> [#uses=1]
This implements Transforms/InstCombine/store-merge.ll:test2
