35071a0847 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.

4b945500a5 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.

57578766aa 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.

f5fd499791 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.
