f0ba0c54ec Add back a couple checks removed by r129128; the fact that an intitializer 
is an array of structures doesn't imply it's a ConstantArray of
ConstantStruct.

f7623daa2b Fix a bug where RecursivelyDeleteTriviallyDeadInstructions could 
delete the instruction pointed to by CGP's current instruction
iterator, leading to a crash on the testcase.  This fixes PR9578.

e8dfbaef19 Avoid excess precision issues that lead to generating host-compiler-specific code. 
Switch lowering probably shouldn't be using FP for this.  This resolves PR9581.

d3b1c5df33 PR9604; try to deal with RAUW updates correctly in the AST. I'm not convinced 
it's completely safe to cache the AST across LICM runs even with this fix,
but this fix can't hurt.

9308e08aad fix PR9629 - We were lowering regexes like a{{b|c}}d into ab|cd, which 
is substantially different than a(b|c)d.  Form the latter regex instead.
This found a few problems in the testsuite, which serves as its test.

5add6d16b7 Build the Hopfield network incrementally when splitting global live ranges. 
It is common for large live ranges to have few basic blocks with register uses
and many live-through blocks without any uses. This approach grows the Hopfield
network incrementally around the use blocks, completely avoiding checking
interference for some through blocks.

b530849e81 Precompute interference for neighbor blocks as long as there is no interference. 
This doesn't require seeking in the live interval union, so it is very cheap.

0c1aa958e2 Redirected errors from the AsmParser to the proper 
error stream, in cases where the AsmParser is
being invoked by EDDisassembler.  Before, they
were being sent to errs() because no error handler
was installed in the SourceMgr.

39ac307002 Do not emit DW_AT_upper_bound and DW_AT_lower_bound for unbouded array. 
If lower bound is more then upper bound then consider it is an unbounded array.
An array is unbounded if non-zero lower bound is same as upper bound.
If lower bound and upper bound are zero than array has one element.

5e0618da1a Mark hasExtraDefRegAllocReq=1 on LDRD. 
The previous cleanup of LDRD got overzealous and removed it, causing post-RA
scheduling to get overzealous in breaking antidependencies and invalidate these instructions. Hilarity and invalid assembly ensued.
