e18a54c249 Use vectors instead of hash_maps for issueGaps and conflictLists. 
These hash lookups were a major sink of time because they happen so often!
Also, add option to disable scheduling.

7436df838d Several major fixes, particularly in emitting constant aggregates: 
(1) Padding bytes between structure fields (for alignment) were never
    being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
    were never handled.
(3) Support new model for external/uninitialized/initialized globals.
    Uninitialized globals are no longer emitted since they are external.
    Initialized globals may go either in .bss or in .data.

032dee9564 Don't use %l0 for large operands to a SAVE since it is needed *before* SAVE! 
We now use %g1 instead since that is shared and volatile.

c78e160ede (1) Try to evaluate constant when multiplying 2 constants. 
(2) Use intelligent multiply selection code for array allocas.
(3) Don't use cache padding for alloca'd stack slots!
(4) Bug fix in handling call arguments: was not copying sixth FP arg
    to int reg. when calling a function with no prototype.

dc9d94262d Make sure to handle small negative values hiding as large unsigned longs -- 
this is a common case created by the front-end.

29dd99d98b Major fix: extract ConstantExpr nodes and decompose them into symbolic 
instructions so that (a) constant folding is done automatically before
code generation, and (b) selection does not have to deal with them.
Also, check for ConstantPointerRefs in additional to GlobalValues
when creating a GEP to load a global address.

Value::replaceAllUsesWith works with constants correctly.

bug FuncResolve/2002-08-19-ResolveGlobalVars.ll and gzip looks better.

    constants.

83d105d986 Almost a complete rewrite of FunctionResolution to now resolve functions 
and global variables.

This fixes bug: FuncResolve/2002-08-19-ResolveGlobalVarsEasier.ll
And bug: SingleSource/UnitTests/2002-10-09-ArrayResolution.c

Note that this does not fix bug:
FunctionResolve/2002-08-19-ResolveGlobalVars.ll because replaceAllUsesWith
breaks when a constantexpr is pointing to the thing being replaced.  This
is more of an infrastructure problem than anything.
