cd888f01a4 x86: Add ENDBR32/ENDBR64 at function entries for Intel CET
To support Intel CET, all indirect branch targets must start with
ENDBR32/ENDBR64.  Here is a patch to define endbranch and add it to
function entries in x86 assembly codes which are indirect branch
targets as discovered by running testsuite on Intel CET machine and
visual inspection.

Verified with

$ CC="gcc -Wl,-z,cet-report=error -fcf-protection" CXX="g++ -Wl,-z,cet-report=error -fcf-protection" .../configure x86_64-linux
$ make -j8
$ make -j8 check

with both nasm and yasm on both CET and non-CET machines.

ede04f0a1f build: Fix for windows to allow nasm use
Previously windows build could only use yasm because some procedural items such
as proc_start were not supported by nasm.  This adds a few macros and fixes so
nasm can be used to build on windows.
