e2277de6a7 Emit the ctors in the proper order on ARM/EABI. 
Maybe some targets should use this as well.

ed1cd704e0 Add a "seen blocks" cache to LVI to avoid a linear scan over the whole cache just to remove no blocks from the maps. 
-15% on ARMDisassembler.cpp (Release build).  It's not that great to add another
layer of caching to the caching-heavy LVI but I don't see a better way.

fe35e107cd Check for stack space more intelligently. 
libgcc sets the stack limit field in TCB to 256 bytes above the actual
allocated stack limit.  This means if the function's stack frame needs
less than 256 bytes, we can just compare the stack pointer with the
stack limit.  This should result in lesser calls to __morestack.

d1c3d82afe Fix a bug in the x86-32 code generated for segmented stacks. 
Currently LLVM pads the call to __morestack with a add and sub of 8
bytes to esp.  This isn't correct since __morestack expects the call
to be followed directly by a ret.

This commit also adjusts the relevant test-case.

2b2f028dcc Creating multiple JITs on X86 in multiple threads causes multiple writes (of 
the same value) to this variable. This code could be refactored, but it doesn't
matter since the old JIT is going away. Add tsan annotations to ignore the
race.

7d0d3c2d58 Move global variables in TargetMachine into new TargetOptions class. As an API 
change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.

One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.

b3b2871bbf [arm-fast-isel] After promoting a function parameter be sure to update the 
argument value type.  Otherwise, the sign/zero-extend has no effect on arguments
passed via the stack (i.e., undefined high-order bits).

c477861998 Fix quadratic behavior in InlineFunction by fetching the personality function of the callee once and not for every invoke in the caller. 
The callee is usually smaller than the caller, too. This reduces the compile
time of ARMDisassembler.cpp by 32% (Release build). It still takes ages to
compile though.
