[OpenMP] Add codegen for 'omp_all_memory' reserved locator.

This creates an entry with address=nullptr and flag=0x80.
When an 'omp_all_memory' entry is specified any other 'out' or
'inout' entries are not needed and are not passed to the runtime.

[OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC)

This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.

The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.

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

[clang] Fix computation of number of dependencies using OpenMP iterator,
by Raul Penacoba.

The size of kmp_depend_info and the number of dependencies are computed multiplying the iterator sizes, which not right.
Now size is computed as:

itersize1*numclausedeps1 + itersize2*numclausedeps2 + ... + itersizeN*numclausedepsN

where itersizeX is the size of the iterator and numclausedepsX the number of dependencies in that depend clause.

Size of type of the dependence flag changed from 1 to 4 bytes in clang.
All dependence flags library gets so far and corresponding dependence types:
1 - IN, 2 - OUT, 3 - INOUT, 4 - MUTEXINOUTSET, 8 - INOUTSET.

Loop control variables are private in loop-based constructs and we shall

Currently, those variables are reported as shared in many cases. Moved

to an early semantic stage to correctly handle their attributes.
