Fix the gtest dependency to be included in DEPS only, rather than
in COMPILE_DEPS + DEPS. The former variable is apparently used to
provide unconditional dependencies, while the latter are only used
for non-standalone builds. Since they are concatenated, specifying gtest
in both is redundant. Furthermore, including it in COMPILE_DEPS causes
build failure for standalone builds where 'gtest' target is not present.

into a function.
Most CMake configuration under compiler-rt/lib/*/tests have
almost-the-same-but-not-quite functions of the form add_X_[unit]tests
for compiling and running the tests.
Much of the logic is duplicated with minor variations across different
sub-folders.
This can harm productivity for multiple reasons:
For newcomers, resulting CMake files are very large, hard to understand,
and hide the intention of the code.
Changes for enabling certain architectures end up being unnecessarily
large, as they get duplicated across multiple folders.
Adding new sub-projects requires more effort than it should, as a
developer has to again copy-n-paste the configuration, and it's not even
clear from which sub-project it should be copy-n-pasted.
With this change the logic of compile-and-generate-a-set-of-tests is
extracted into a function, which hopefully makes writing and reading
CMake much easier.

This patch addresses two issues:
Most of the time, hacks with `if/else` in order to get support for
multi-configuration builds are superfluous.
The variable `CMAKE_CFG_INTDIR` was created precisely for this purpose: it
expands to `.` on all single-configuration builds, and to a configuration
name otherwise.
The `if/else` hacks for the library name generation should also not be
done, as CMake has `TARGET_FILE` generator expression precisely for this
purpose, as it expands to the exact filename of the resulting target.

The first instruction of the new ucrtbase!strnlen implementation loads a
global, presumably to dispatch between SSE and non-SSE optimized strnlen
implementations.

This fix a bug, when calling InternalGetProcAddress() for an executable that
doesn't export any symbol. So the table is empty.
If we don't check for this condition, the program fails with Error 0xc0000142.
Also, I add a regression test for Windows.

Summary:
In a 32-bit address space, PC-relative jump targets are wrapped, so a
direct branch at 0x90000001 can reach address 0x10000000 with a
displacement of 0x7FFFFFFFF. This can happen in applications, such as
Chrome, that are linked with /LARGEADDRESSAWARE.

Summary:
This patch is fixing a broken unittest which make the win64 bot failing.
The bug was introduce here:
https://reviews.llvm.org/D23046
The interception code is not the same in 32-bit and in 64-bit.
The added unittest can only be patched on 32-bits.

Summary:
On my install of Windows 10, RaiseException is a tail call to
kernelbase!RaiseException. Obviously, we fail to intercept that.
Instead, try hooking at the ntdll!RtlRaiseException layer. It is
unlikely that this layer will contain control flow.
Intercepting at this level requires adding a decoding for
'LEA ESP, [ESP + 0xXXXXXXXX]', which is a really obscure way to write
'SUB ESP, 0xXXXXXXXX' that avoids clobbering EFLAGS.

mov edi,edi is _not_ NOP in 64-bit, use 66,90h instead.
This bug was causing interception unittest to crash on
Windows64 (windows 8 and windows 10).
