[SystemZ] Update non-pic DWARF encodings
As pointed out by Rafael Espindola, we should match the DWARF encodings
produced by GCC in both pic and non-pic modes. This was not the case
for the non-pic case.
This patch changes all DWARF encodings to DW_EH_PE_absptr for the

Simplify JIT unit test #ifdefs
Several platforms need to disable all old-JIT unit tests, since they only
support the new MCJIT. This currently done via #ifdef'ing out those tests
in the ExecutionEngine/JIT/*.cpp files. As those #ifdef's have grown
historically, we now have a number of repeated directives which -in total-
cover nearly the whole file, but leave a couple of helper functions out.
When building the tests with clang itself, those helper functions now
cause spurious "unused function" warnings.
To fix those warnings, and also to remove the duplicate #ifdef conditions
and make it easier to disable the tests for a new target, this patch
consolidates the #ifdefs into a single one per file, which covers all
the tests including all helper routines.

PatternMatch: Matcher for (un)ordered floating point min/max
Add support for matching 'ordered' and 'unordered' floating point min/max
constructs.
In LLVM we can express min/max functions as a combination of compare and select.
We have support for matching such constructs for integers but not for floating
point. In floating point math there is no total order because of the presence of
'NaN'. Therefore, we have to be careful to preserve the original fcmp semantics
when interpreting floating point compare select combinations as a minimum or
maximum function. The resulting 'ordered/unordered' floating point maximum
function has to select the same value as the select/fcmp combination it is based
on.
ordered_max(x,y) = max(x,y) iff x and y are not NaN, y otherwise
unordered_max(x,y) = max(x,y) iff x and y are not NaN, x otherwise
ordered_min(x,y) = min(x,y) iff x and y are not NaN, y otherwise
unordered_min(x,y) = min(x,y) iff x and y are not NaN, x otherwise
This matches the behavior of the underlying select(fcmp(olt/ult/.., L, R), L, R)
construct.
Any code using this predicate has to preserve this semantics.
A follow-up patch will use this to implement floating point min/max reductions
in the vectorizer.

AArch64: add stubs to support long function calls on MCJIT
As with global accesses, external functions could exist anywhere in

patch implements the fragment as (roughly):
movz x16, #:abs_g3:somefunc
movk x16, #:abs_g2_nc:somefunc
movk x16, #:abs_g1_nc:somefunc
movk x16, #:abs_g0_nc:somefunc

In principle we could save 4 bytes by using a literal-load instead,

[mips] Split the DSP control register and define one register for each field of
its fields.
This removes false dependencies between DSP instructions which access different
fields of the the control register. Implicit register operands are added to
instructions RDDSP and WRDSP after instruction selection, depending on the
value of the mask operand.

LoopVectorizer: Add support for if-conversion of PHINodes with 3+ incoming values.
By supporting the vectorization of PHINodes with more than two incoming values we can increase the complexity of nested if statements.
We can now vectorize this loop:
int foo(int *A, int *B, int n) {
for (int i=0; i < n; i++) {
int x = 9;
if (A[i] > B[i]) {
if (A[i] > 19) {
x = 3;
} else if (B[i] < 4 ) {
x = 4;
} else {
x = 5;
}
}
A[i] = x;
}
}
