54a3f2b134 *** 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

60d2a51347 * Finegrainify namespacification 
* Strength reduce several data structures which were left over from the
  "bad old days"
* 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

7164a8a7ea 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.

c6a7c83333 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.

c4f8226aaf Emit x86 instructions for: A = B op C, where A and B are 16-bit registers, 
C is a constant which can be sign-extended from 8 bits without value loss,
and op is one of: add, sub, imul, and, or, xor.

This allows the JIT to emit the one byte version of the constant instead of
the two or 4 byte version.  Because these instructions are very common, this
can save a LOT of code space.  For example, I sampled two benchmarks, 176.gcc
and 254.gap.

BM        Old     New    Reduction
176.gcc 2673621 2548962  4.89%
254.gap  498261  475104  4.87%

Note that while the percentage is not spectacular, this did eliminate
124.6 _KILOBYTES_ of codespace from gcc.  Not bad.

Note that this doesn't effect the llc version at all, because the assembler
already does this optimization.

27798b47fb Without this option, the -run-llc mode does not work with shared objects at 
all, making it pointless for use with the code generator debugger.  With it,
it works like a charm.

2bdaaa4e08 Add support for 'weak' linkage. 
For now, we translate linkonce into weak linkage in the bytecode format because
we don't have enough bits to represent it.  We will rev the bytecode version
soon anyways, so this will be fixed in the near future.

09ef1749f7 Completely rewrite support for the Value::use_* list. Now, all operations on 
this list (except use_size()) are constant time.  Before the killUse method
(used whenever something stopped using a value) was linear time, and thus
very very slow for large programs.

This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc:

176.gcc:     77.07s -> 37.38s
177.mesa:     7.59s ->  5.57s
252.eon:     21.02s -> 19.52s (*)
253.perlbmk: 11.40s -> 13.05s
254.gap:      7.25s -> 7.42s

252.eon would speed up a whole lot more, but optimization time is being
dominated by the inlining pass, which needs to be fixed.
