dfc8fbf16b - Two minor improvements to the MachineInstr class to reduce footprint and 
overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
    bitvector.  Sped up LLC a little less than 10% in a debug build!

b16f596ab4 Allow emission of names that start with an underscore. This is needed to 
interface with code that uses symbols in the ansi-c protected namespace.  In
most cases this comes from system header files, such as stdio.h.  In particular,
without this change, a reference to the __iob symbol is mangled into ll_iob,
which is not resolved by libc.

fdf2ca9468 - Rename Instruction::First*Op to *OpsBegin, and Num*Ops to *OpsEnd to 
reflect the fact that it's a range being defined.

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.

06742cc0e0 Live ranges for Return value and return address of a Call are no longer

940f3fa91b Overhaul integer conversions to match C++ ISO standard. 
Don't allow direct FP-to-uint conversion (must be eliminated by preselection).
Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed.
