2ceee2f884 Add -Wno-strict-prototypes to C tests; NFC
This patch adds -Wno-strict-prototypes to all of the test cases that
use functions without prototypes, but not as the primary concern of the
test. e.g., attributes testing whether they can/cannot be applied to a
function without a prototype, etc.

This is done in preparation for enabling -Wstrict-prototypes by
default.

adc402bf3d 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 eleventh batch of tests being updated (there are a
significant number of other tests left to be updated).

fd739804e0 [test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences
For a default visibility external linkage definition, dso_local is set for ELF
-fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar
to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences.

To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition,
which sets dso_local for default visibility external linkage definitions.

To make this flip smooth and enable future (dso_local as definition default),
this patch replaces (function) `define ` with `define{{.*}} `,
(variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

7fef551cb1 Revert "Revert "[FPEnv] Teach the IRBuilder about invoke's correct use of the strictfp attribute.""
Similar to D69312, and documented in D69839, the IRBuilder needs to add
the strictfp attribute to invoke instructions when constrained floating
point is enabled.

This is try 2, with the test corrected.

2ec5973fdd Revert "[FPEnv] Teach the IRBuilder about invoke's correct use of the strictfp attribute."
The test is busted on some hosts that aren't the one I'm using.

This reverts commit 67a1ffd88ac08526bb6cfc7b3f607e6668ba1c70.
