Aaron Ballman e765e0bc8e Use functions with prototypes when appropriate; NFC 
A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,

  void func();

becomes

  void func(void);

This is the first batch of tests being updated (there are a significant
number of other tests left to be updated).

Zahira Ammarguellat fd759d42c9 Revert "The _Float16 type is supported on x86 systems with SSE2 enabled." 
This reverts commit 6623c02d70.
The change seems to be breaking build of compiler-rt on Debian.

Zahira Ammarguellat 6623c02d70 The _Float16 type is supported on x86 systems with SSE2 enabled. 
Operations are emulated by software emulation and “float” instructions.
This patch is allowing the support of _Float16 type without the use of
-max512fp16 flag. The final goal being, perform _Float16 emulation for
all arithmetic expressions.

Richard Smith 6c18f7db73 For PR46800, implement the GCC __builtin_complex builtin. 
glibc's implementation of the CMPLX macro uses it (with -fgnuc-version
set to 4.7 or later).

Erich Keane 1d1d438e8e Disable _Float16 for non ARM/SPIR Targets 
As Discussed here:
http://lists.llvm.org/pipermail/llvm-dev/2019-January/129543.html

There are problems exposing the _Float16 type on architectures that
haven't defined the ABI/ISel for the type yet, so we're temporarily
disabling the type and making it opt-in.
