Chris Lattner 1a02ca932c *** Significantly speed up type resultion 
This change speeds up type resolution by checking to see if a type is
  recursive, and if it's not, using a more efficient algorithm.

  This dramatically reduces bytecode loading time of kc++, reducing time-to-jit
  kc++ --version to 17s from 33s

Chris Lattner 9c68fa3ab1 * Finegrainify namespacification 
* Strength reduce several data structures which were left over from the

* Minor efficiency improvements
* Major efficiency improvement: In BytecodeParser::insertValue, do not allocate
  a new ValueTab entry just because some value exists with a large type.  This
  dramatically reduces the number of allocations/deallocations performed by the
  bytecode reader, and speeds up parsing of Kimwitu++ from 34s to 17s.  This is
  to help address PR127

Chris Lattner 9005b8000c ISO 9899 7.13.2.1 (3) says that "[...] the values of objects of automatic 
storage duration that are local to the function containing the invocation of the
[...] setjmp macro that do not have volatile-qualified type and have been
changed between the setjmp invocation and longjmp call are indeterminate."

As such, we have to mark all variables in a function that uses 'invoke' as
volatile.

each instruction produces as "operand" -1, and the other operands as 0
.. n, as before. PhyRegAlloc::saveState() is refactored into

Chris Lattner 984e11792f Do NOT inline self recursive calls into other functions. This is causing the 
pool allocator no end of trouble, and doesn't make a lot of sense anyway.  This
does not solve the problem with mutually recursive functions, but they are much less common.

Misha Brukman 3b2343eae9 PreSelection is not optional, it performs a necessary and vital transformation

Alkis Evlogimenos 9118a426d3 Change all machine basic block modifier functions in MRegisterInfo to 
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.
