outweight its computational costs. This patch removes all compaction
table handling from the bcreader and bcwriter. For the record, here's the
difference betweeen having and not having compaction tables for some tests:
Test With Without Size Chg
Olden/mst 5,602 5,598 +0.1%
viterbi 18,026 17,795 +1.3%
obsequi 162,133 166,663 -2.8%
burg 224,090 228,148 -1.8%
kimwitu++ 4,933,263 5,121,159 -3.8%
176.gcc 8,470,424 9,141,539 -7.3%
It seems that it is more beneficial to larger files, but even on the largest
test case we have (176.gcc) it only amounts ot an I/O saving of 7.3%.

Update these tests to not use the same name even though the type of the
value differs. After PR411 hits, type planes will be gone and it will be
illegal for a name to be used twice, regardless of type.

spilled (if it is not already).
- If LR is spilled, use BL to implement far jumps. LR is not used as a GPR
in thumb mode so it can be clobbered if it is properly spilled / restored
in prologue / epilogue.
- If LR is force spilled but no far jump has been emitted, try undo'ing the
spill by:
push lr -> delete
pop pc -> bx lr

This doesn't do the "right thing" but will probably work in most cases.

PassManagers.h).
- Add StopPassTimer() and StartPassTimer() to expose TimingInfo to
CallGraphPassManager
- Use these two APIs in CalLgraphPassManager to measure timings.

When an unresolved definition is found, check to see if it is only unresolved
because the csretcc was upgraded to the sret param attribute. Such changes
change the function type and lead to unresolved definitions. In such cases, just
cast the function to the type expected by the CallInst. That is, cast to the
version of the function that has the sret param attribute.

functions like memcpy, memmove and memset. Ensure only one prototype is
used for these functions and that it matches the system definition by
using the appropriate type for the size argument.

Fix initializeConstant, now initializeInt. Fixes major performance
bottleneck.
X == Y || X->DominatedBy(Y) is redundant. Remove the X == Y part.
Fix crasher in makeEqual where getOrInsertNode would add a new constant,
producing an NE relationship between the two members we're trying to make
equal. This now allows us to mark more BBs as unreachable.
