    Revert of MIPS: Fix '[turbofan] Prevent storing signalling NaNs into holey double arrays.' (patchset #2 id:20001 of https://codereview.chromium.org/2171303002/ )
    
    Reason for revert:
    This bug has an error in the toolchain.gypi file, the conditions clause is repeated. This has broken the DrMemory builder - see first failing chromium build https://build.chromium.org/p/chromium.memory.fyi/builders/Chromium%20Windows%20Builder%20%28DrMemory%29/builds/17857 which included a v8 roll.
    
    For reference the errors are:
    gyp: Key 'conditions' repeated at level 11 with key path 'target_defaults.conditions.6.1.target_conditions.0.1.conditions.0.1' while reading C:\b\build\slave\drm-cr\build\src\v8\gypfiles\toolchain.gypi while reading includes of C:\b\build\slave\drm-cr\build\src\v8\src\d8.gyp

    Original issue's description:
    > MIPS: Fix '[turbofan] Prevent storing signalling NaNs into holey double arrays.'
    >
    > Port 6470ddad
    >
    > On MIPS different signaling NaN values must be used for hardware and simulator targets, even at snapshot generation when always simulator is used.
    >
    > Original commit message:
    > This introduces SilenceNaN operator, which makes sure that we only
    > store quiet NaNs into holey arrays. We omit the NaN silencing code
    > at instruction selection time if the input is an operation that
    > cannot possibly produce signalling NaNs.
