Reland: change most cases of variable redeclaration from TypeError to SyntaxError. Reland of https://codereview.chromium.org/2048703002/ Code like `let a; eval("var a;");` should throw a SyntaxError, not a TypeError (this caused a test262 failure.). However, the code `eval("function NaN() {}");` should actually throw a TypeError. This patch changes most cases of redeclaration errors from TypeError to SyntaxError. See the test mjsunit/regress/redeclaration-error-types for a thorough analysis with spec references. The relevant sections of the spec are ES#sec-globaldeclarationinstantiation and ES#sec-evaldeclarationinstantiation BUG=v8:4955 LOG=y CQ_INCLUDE_TRYBOTS=tryserver.blink:linux_blink_rel R=adamk Review-Url: https://codereview.chromium.org/2086063002 Cr-Commit-Position: refs/heads/master@{#37156}
