build: add OpenSSL-1.1.0 support

- For Windows, nasm is new build requirements and openssl_no_asm is
  set to 1 with warning if it is not installed.
- For use of openssl assemble codes, either gas_version >= 2.23,
  xcode_version >= 5.0 ,llvm_version >= 3.3 or nasm_version >= 2.10 is
  needed. Otherwise, openssl_no_asm is set to 1 with warning.
- FIPS is not supported in OpenSSL-1.1.0 so that it leads an error
  when openssl_fips options is enabled in configure.

+OpenSSL-1.1.0 requires the following asssembler version for use of asm
+support.
+
+* gas (GNU assembler) version 2.23 or higher
+* xcode version 5.0 or higher
+* llvm version 3.3 or higher
+* nasm version 2.10 or higher in Windows

+Otherwise, `--openssl-no-asm` is added with warning in configure.

 ## Building Node.js with FIPS-compliant OpenSSL
 
-It is possible to build Node.js with the
-[OpenSSL FIPS module](https://www.openssl.org/docs/fipsnotes.html) on POSIX
-systems. Windows is not supported.
-
-Building in this way does not mean the runtime is FIPS 140-2 validated, but
-rather that the runtime uses a validated module. In addition, the validation for
-the underlying module is only valid if it is deployed in accordance with its
-[security policy](http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf).
-If you need FIPS validated cryptography it is recommended that you read both
-the [security policy](http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf)
-and [user guide](https://openssl.org/docs/fips/UserGuide-2.0.pdf).
-
-### Instructions
-
-1. Obtain a copy of openssl-fips-x.x.x.tar.gz.
-   To comply with the security policy you must ensure the path
-   through which you get the file complies with the requirements
-   for a "secure installation" as described in section 6.6 in
-   the [user guide](https://openssl.org/docs/fips/UserGuide-2.0.pdf).
-   For evaluation/experimentation, you can simply download and verify
-   `openssl-fips-x.x.x.tar.gz` from https://www.openssl.org/source/
-2. Extract source to `openssl-fips` folder and `cd openssl-fips`
-3. `./config`
-4. `make`
-5. `make install`
-   (NOTE: to comply with the security policy you must use the exact
-   commands in steps 3-5 without any additional options as per
-   Appendix A in the [security policy](http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf).
-   The only exception is that `./config no-asm` can be
-   used in place of `./config`, and the FIPSDIR environment variable
-   may be used to specify a non-standard install folder for the
-   validated module, as per User Guide sections 4.2.1, 4.2.2, and 4.2.3.
-6. Get into Node.js checkout folder
-7. `./configure --openssl-fips=/path/to/openssl-fips/installdir`
-   For example on ubuntu 12 the installation directory was
-   `/usr/local/ssl/fips-2.0`
-8. Build Node.js with `make -j`
-9. Verify with `node -p "process.versions.openssl"` (for example `1.0.2a-fips`)
+This version of Node.js does not support FIPS.
