to be executed with the runtime library present in DYLD_INSERT_LIBRARIES list.
Therefore if it's initially missing in that list, we append the runtime library name
to the value of DYLD_INSERT_LIBRARIES and then exec() ourselves.

ASan runtime library preloaded, so we remove the runtime library from the

BBVectorize: Cap the number of candidate pairs in each instruction group
For some basic blocks, it is possible to generate many candidate pairs for
relatively few pairable instructions. When many (tens of thousands) of these pairs
are generated for a single instruction group, the time taken to generate and
rank the different vectorization plans can become quite large. As a result, we now
cap the number of candidate pairs within each instruction group. This is done by
closing out the group once the threshold is reached (set now at 3000 pairs).
Although this will limit the overall compile-time impact, this may not be the best
way to achieve this result. It might be better, for example, to prune excessive
candidate pairs after the fact the prevent the generation of short, but highly-connected
groups. We can experiment with this in the future.
This change reduces the overall compile-time slowdown of the csa.ll test case in
PR15222 to ~5x. If 5x is still considered too large, a lower limit can be
used as the default.
This represents a functionality change, but only for very large inputs
(thus, there is no regression test).

The purpose of this change is to simplify creating non-atom sections.

into AtomSection and makes Section just have raw Elf_Shdr flags.

[analyzer] Try constant-evaluation for all variables, not just globals.
In C++, constants captured by lambdas (and blocks) are not actually stored
in the closure object, since they can be expanded at compile time. In this
case, they will have no binding when we go to look them up. Previously,
RegionStore thought they were uninitialized stack variables; now, it checks
to see if they are a constant we know how to evaluate, using the same logic
as r175026.
This particular code path is only for scalar variables. Constant arrays and
structs are still unfortunately unhandled; we'll need a stronger solution
for those.
This may have a small performance impact, but only for truly-undefined
local variables, captures in a non-inlined block, and non-constant globals.
Even then, in the non-constant case we're only doing a quick type check.

R600/SI: Fix int_SI_fs_interp_constant
The important fix is that the constant interpolation value is stored in the
parameter slot P0, which is encoded as 2.
In addition, drop the SI_INTERP_CONST pseudo instruction, pass the parameter
slot as an operand to V_INTERP_MOV_F32 instead of hardcoding it there, and
add a special operand class for the parameter slots for type checking and
pretty printing.
NOTE: This is a candidate for the Mesa stable branch.
