93b617fac4 Add a method to get a StringMapEntry from a pointer to the string 
data it contains (similar to GetStringMapEntryFromValue).

a9eb6a6987 add some accessors to callsite/callinst/invokeinst to check 
for the noinline attribute, and make the inliner refuse to
inline a call site when the call site is marked noinline even
if the callee isn't.  This fixes PR6682.

needed here.

7814ddee81 Remove getTypeToExpandTo, since it isn't adding much value 
beyond just calling getTypeToTransformTo.

ae8d914c58 MC: Tweak MCInstFragment to include the encoded data and fixups, so that we don't need to recompute them during relaxation. I will revisit this once all the other pieces of fast relaxation are in place.

we can reapply the InvokeInst operand reordering patch. (see r98957).

abb84bec5c Add a setCalledFunction member to InvokeInst (like in CallInst)

92d4663789 Clear the SCEVExpander's insertion point after making deletions, 
so that the SCEVExpander doesn't retain a dangling pointer as its
insert position. The dangling pointer in this case wasn't ever used
to insert new instructions, but it was causing trouble with
SCEVExpander's code for automatically advancing its insert position
past debug intrinsics.

This fixes use-after-free errors that valgrind noticed in
test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and
test/Transforms/IndVarSimplify/exit_value_tests.ll.

a537af16ce Fix more places to more thoroughly ignore debug intrinsics. This fixes 
use-before-def errors in SCEVExpander-produced code in sqlite3 when debug
info with optimization is enabled, though the testcases for this are
dependent on use-list order.

766909ae3b Fixed the encoding problems of the crc32 instructions. All had the Operand size 
override prefix and only the r/m16 forms should have had that.  Also for variant
one, the AT&T syntax, added suffixes to all forms.  Also added the missing
64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
tweaked one test case to add the needed suffixes.

42ef17e8b6 Stop trying to merge identical jump tables. This had been inadvertently 
disabled for several months (since svn r88806) and no one noticed.  My fix
for pr6543 yesterday reenabled it, but broke the ARM port's code for using
TBB/TBH.  Rather than adding a target hook to disable merging for Thumb2 only,
I'm just taking this out.  It is not common to have identical jump tables,
the code we used to merge them was O(N^2), and it only helps code size, not
performance.

953702b8e6 Recommit r80858 again (which has been backed out in r80871). 
This time I did a self-hosted bootstrap on Linux x86-64,
with no problems. Let's see how darwin 64-bit self-hosting
goes. At the first sign of failure I'll back this out.

Maybe the valgrind bots give me a hint of what may be wrong
(it at all).

6b395fca87 add a new SDNPVariadic SDNP node flag, and use it in
