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).

This patch adds support for the TME instructions TSTART, TTEST, TCOMMIT, and
TCANCEL and the target feature/arch extension "tme".

It also implements TME builtin functions, defined in ACLE Q2 2019
