      Fix a warning about inline asm source/destination mismatches for cache_type_register_. · d6d82306
      echristo authored 
      The warning notes that we'd want a 'w' register here because the size of
the operand is 32-bit, however, the instruction only takes an 'x'
register and so force that using the 'x' modifier on the instruction.

      S390: [stubs] Split ToNumberStub into reusable subparts. · 0503ba76
      jyan authored 
      Port b7aa4c3a

Original commit message:
    Split ToNumberStub into the entry ToNumberStub, and two new stubs,
    StringToNumberStub and NonNumberToNumberStub, which can be used when we
    already know something about the input (i.e. in various branches of the
    code stubs, or in TurboFan graphs).

    Also introduce an appropriate StringToNumber simplified operator for
    TurboFan, that is pure and is lowered to an invocation of the newly
    added StringToNumberStub.

      S390: [crankshaft] Fixing ES6 tail call elimination. · 716ab0d3
      jyan authored 
      Port acbb968d
Port 66e22b79

Original commit messages:
    In case when F inlined normal call to G which tail calls H we should not write translation for G for the tail call site.
    Otherwise we will see G in a stack trace inside H.

    This CL also enables all existing tests related to ES6 tail call elimination and adds more combinations.

    Always generate lazy bailout points for tail calls because Debugger could still require them to inspect optimized frames.

      Remove support for legacy const, part 1 · ed18aa65
      adamk authored 
      Now that ES2015 const has shipped, in Chrome 49, legacy const declarations
are no more. This lets us remove a bunch of code from many parts of the
codebase.

In this patch, I remove parser support for generating legacy const variables
from const declarations. This also removes the special "illegal declaration"
bit from Scope, which has ripples into all compiler backends.

Also gone are any tests which relied on legacy const declarations.

Note that we do still generate a Variable in mode CONST_LEGACY in one case:
function name bindings in sloppy mode. The likely fix there is to add a new
Variable::Kind for this case and handle it appropriately for stores in each
backend, but I leave that for a later patch to make this one completely
subtractive.

      Fix match default behavior on strings for ES2015 semantics · 64b2b1ac
      littledan authored 
      String.prototype.match is specified to call out to the current
value of RegExp.prototype[Symbol.match] when passed a string argument,
rather than the original value. This patch updates the RegExp code
to do that.

      S390:[crankshaft] Sign-ext key before array access · bdcefb9d
      joransiu authored 
      The 'key' value being passed into an array access should
be sign-extended on 64-bit platforms before being used to
index into memory.  Otherwise, garbage in the upper 32-bits
may result in a segmentation fault.

Minor fix to DoFlooringDivI to enforce 32-bit operations for calculation.
