3d0157ae7e Disable physical register coalescing when the number of live ranges for the 
physreg becomes ridiculously high.

std::upper_bound may be log(N), but for sufficiently large live intervals, it
becomes log(N)*cachemiss = a long long time.

This patch improves coalescer time by 4500x for a function with 20000
function calls. The generated code is different, but not significantly worse -
the allocator hints are almost as good as physreg coalescing anyway.

4995bb0450 Start using DIFile. See updated SourceLevelDebugging.html for more information. 
This patch updates LLVMDebugVersion to 8.
Debug info descriptors encoded using LLVMDebugVersion 7 is supported.

Corresponding llvmgcc and clang FE commits are required.

183e87502e now that the debug and eh emitters use a common .set counter,

10d571f349 simplify EmitSectionOffset to always use .set if it is 
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.

116599fe52 Fix a crash compiling 254.gap for Thumb2. The Thumb2 add/sub with 12-bit 
immediate instructions cannot set the condition codes, so they do not have
the extra cc_out operand.  We hit an assertion during tail duplication
because the instruction being duplicated had more operands that expected.
