David Benjamin 9b5028523f Check in a pristine copy of googletest. 
Snapshotted from 5e7fd50e17b6edf1cadff973d0ec68966cf3265e in the
upstream repository:
https://github.com/google/googletest

Since standalone builds and bots will need this, checking in a copy
rather than require everyone use gclient, repo, git submodules or scary
CMake scripts is probably simplest.

Consumers with their own copies of googletest will likely wish to ignore
or even exclude this directory.

// A class for indicating whether an assertion was successful. When
// the assertion wasn't successful, the AssertionResult object
// remembers a non-empty message that describes how it failed.
//
// To create an instance of this class, use one of the factory functions
// (AssertionSuccess() and AssertionFailure()).
//
// This class is useful for two purposes:
// 1. Defining predicate functions to be used with Boolean test assertions
// EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
// 2. Defining predicate-format functions to be
// used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
//
// For example, if you define IsEven predicate:
//
// testing::AssertionResult IsEven(int n) {
// if ((n % 2) == 0)
// return testing::AssertionSuccess();
// else
// return testing::AssertionFailure() << n << " is odd";
// }
//
// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
// will print the message
//
// Value of: IsEven(Fib(5))
// Actual: false (5 is odd)
// Expected: true
//
// instead of a more opaque
//
// Value of: IsEven(Fib(5))
// Actual: false
// Expected: true
//
// in case IsEven is a simple Boolean predicate.
//
// If you expect your predicate to be reused and want to support informative
// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
// about half as often as positive ones in our tests), supply messages for
// both success and failure cases:
//
// testing::AssertionResult IsEven(int n) {
// if ((n % 2) == 0)
// return testing::AssertionSuccess() << n << " is even";
// else
// return testing::AssertionFailure() << n << " is odd";
// }
//
// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
//
// Value of: IsEven(Fib(6))
// Actual: true (8 is even)
// Expected: false
//
// NB: Predicates that support negative Boolean assertions have reduced
// performance in positive ones so be careful not to use them in tests
// that have lots (tens of thousands) of positive Boolean assertions.
//
// To use this class with EXPECT_PRED_FORMAT assertions such as:
//
// // Verifies that Foo() returns an even number.
// EXPECT_PRED_FORMAT1(IsEven, Foo());
//
// you need to define:
//
// testing::AssertionResult IsEven(const char* expr, int n) {
// if ((n % 2) == 0)
// return testing::AssertionSuccess();
// else
// return testing::AssertionFailure()
// << "Expected: " << expr << " is even\n Actual: it's " << n;
// }
//
// If Foo() returns 5, you will see the following message:
//
// Expected: Foo() is even
// Actual: it's 5

// are related, not how their content is related. To compare two C
// strings by content, use {ASSERT|EXPECT}_STR*().
