Neil Carlson e9c984267e NAG: Use -PIC for Fortran position-independent executable code
The Numerical Algorithms Group (NAG) Fortran compiler documents -PIC for
position-independent code and does not have a separate option for PIE.
We added `-PIC` for PIC in commit v2.8.11~174^2 (NAG: Use -PIC for
Fortran position-independent code, 2013-02-18).  Follow up for PIE.

Ben Boeckel cc223e1eed Intel-C: declare support for gnu11
Without extensions, functions like `strdup` are not available since they
are actually controlled by feature flags such as _SVID_SOURCE and
_BSD_SOURCE. When using `-std=c11` on Intel, none of these flags are
set, so the functions are not declared properly leading to compile
errors.

Brad King 85e0314201 GNU: Use -fvisibility on GCC 4.0 and 4.1 too
This flag is needed for the `<LANG>_VISIBILITY_PRESET` target property.
It has been supported since GCC 4.0, not 4.2 as we previously recorded.

Fixes #16222.

Brad King a66004bee0 Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in toolchain files
Document these variables.

Change our convention for setting these variables from:

    set(CMAKE_C_FLAGS_INIT "...")

to

    string(APPEND CMAKE_C_FLAGS_INIT " ...")

so that any value previously set by a toolchain file will be used.

Automate the conversion with:

    sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \
      Modules/Compiler/*.cmake Modules/Platform/*.cmake

and follow up with some manual fixes (e.g. to cases that already
meant to append).  Also revert the automated changes to contexts
that are not protected from running multiple times.

Brad King f9dbe22ca2 Intel: Do not use GNU-like flags on Windows
Refactor options out of `Modules/Compiler/Intel-{ASM,C,CXX,Fortran}.cmake`
into a common helper in `Modules/Compiler/Intel.cmake`.  Condition
them to be used only on non-Windows hosts where the Intel compiler
is GNU-like instead of MSVC-like.

Previously this worked only because the options were later overridden
by `Modules/Platform/Windows-Intel*.cmake`, but it is cleaner to not
set the options in the first place.

Gregor Jasny 2cae5128fd Apple: Enable -isystem for GNU Compiler >= 4 (#15953)
Due to #4662 -isystem support was disabled for all GNU Compilers
on Apple platforms. But the change was probably a just work around
for a broken compiler on Tiger (see 10837#c27206). So we tighten
the condition to only kick in for GCC versions earlier than 4.
That should ensure sane behavior for Xcode 3.2 and later.

Chuck Atkins a7ef02253b Cray: Refactor the Cray platform files to use compiler wrapper checks
This is an extensive refactoring of the Cray compiler wrapper usage.
Using the new compiler wrapper checks, the CrayPrgEnv info files have
been moved from Platform/ to Compiler/.  The adjusted naming convention
allows the compiler-wrapper information files to be loaded for both the
CrayLinuxEnvironment platform when cross-compiling and the Linux
platform if building natively on the Cray compute nodes.  It also
creates a separation of common arguments for compiler id and language
information used to perform the appropriate introspection of implicit
arguments and libraries used by the compiler wrappers based on the
loaded module environment.

James Johnston 7a3277276e Embarcadero: Fix erroneous interpretation of __CODEGEARC_VERSION__.
As per the following link:

  http://docwiki.embarcadero.com/RADStudio/Seattle/en/Example_of_CODEGEARC_VERSION_Macro

The major/minor versions must be decoded as a hex string, while the patch
version must be decoded as a normal decimal string.

As an example, C++ Builder XE 8.1's bcc32.exe sets this macro to 0x070189C9.
The file version of bcc32.exe is 7.1.5570.35273.  Therefore, the correct
interpretation to COMPILER_VERSION would be 7.1.35273.

Brad King 441dba8032 Project: Guess default standard dialect if compiler was forced (#15852)
Prior to commit v3.4.0-rc1~71^2 (Project: Determine default language
dialect for the compiler, 2015-09-15) we always guessed the default
language standard dialect based on the compiler version.  This was not
reliable so that commit switched to computing the default language
standard dialect while detecting the compiler id.

When a toolchain file uses CMakeForceCompiler to set the compiler id
then the detection does not occur.  Therefore commit v3.4.0-rc1~54^2
(Project: Don't require computed default dialect if compiler was forced,
2015-09-22) made the lack of detection an error only if the compiler was
not forced.  However, this means that projects using CMakeForceCompiler
no longer even get the guess that we had before so <LANG>_COMPILER does
not work.

Due to the sophistication of CMake's compiler detection logic projects
should be ported away from using CMakeForceCompiler.  In the meantime,
restore a guess of the default language standard dialect when the
compiler is forced.

Stephen Kelly d13758514c Project: Don't require computed default dialect if compiler was forced.
Commit 7235334a (Project: Determine default language dialect for the
compiler., 2015-09-15) introduced a mechanism to determine the default
dialect used for the running compiler.  If conditions in
the <CompilerId>-<Lang>.cmake file are such that compile features for
that version of the compiler should be supported, the _DEFAULT_STANDARD
is set to the computed value.

However, the CMakeForceCompiler module allows users to bypass execution of the
compiler by CMake.  In that case, do not set the _DEFAULT_STANDARD variable at
all, which effectively disables the compile-features where the module is used.

No compile features have ever been recorded where the module is used so no
functionality is lost.
