Dan Gohman 2f16f25391 [WebAssembly] Don't special-case call operand order.
With the '=' suffix now indicating which operands are output operands, it's
no longer as important to distinguish between a call's inputs and its outputs
using operand ordering, so we can go back to printing them in the normal order.

64x32, 128x8, 128x16, 256x8, 512x1, and 1024x1.

Dan Gohman 700515fa92 [WebAssembly] Suffix output operands with '='.
This distinguishes input operands from output operands. This is something of
a syntactic experiment to see whether the mild amount of clutter this adds is
outweighed by the extra information it conveys to the reader.

Summary:
For relocation types that are known to not require stub functions, there

Sanjoy Das 277776a520 [RuntimeDyld] Add accessors to `SectionEntry`; NFC
Summary:
Remove naked access to the data members in `SectionEntry` and route
accesses through accessor functions.  This makes it obvious how the
instances of the class are used, and will also facilitate adding bounds
checking to `advanceStubOffset` in a later change.

- dump raw/indexed format into text profile format
- merge the profile and output into text profile format.

Note that Value Profiling data text format is not yet designed. 
That functionality will be added later.

Diego Novillo 243ea6a7d6 SamplePGO - Add coverage tracking for samples.
The existing coverage tracker counts the number of records that were used
from the input profile. An alternative view of coverage is to check how
many available samples were applied.

This way, if the profile contains several records with few samples, it
doesn't really matter much that they were not applied. The more
interesting records to apply are the ones that contribute many samples.

Ehsan Akhgari 93697fa755 Make clang_Cursor_getMangling not mangle if the declaration isn't mangled
Right now clang_Cursor_getMangling will attempt to mangle any
declaration, even if the declaration isn't mangled (extern C).  This
results in a partially mangled name which isn't useful for much. This
patch makes clang_Cursor_getMangling return an empty string if the
declaration isn't mangled.

Dan Gohman aa0a4bd05b [WebAssembly] Don't use set_local instructions explicitly.
The current approach to using get_local and set_local is to use them
implicitly, as register uses and defs. Introduce new copy instructions
which are themselves no-ops except for the get_local and set_local
that they imply, so that we use get_local and set_local consistently.

Dan Gohman f6857223c9 [WebAssembly] Always print loop end labels
WebAssembly is currently using labels to end scopes, so for example a
loop scope looks like this:

BB0_0:
  loop BB0_1
  ...
BB0_1:

with BB0_0 being the label of the first block not in the loop. This
requires that the label be printed even when it's only reachable via
fallthrough. To arrange this, insert a no-op LOOP_END instruction in
such cases at the end of the loop.

Martell Malone f6301faa8b Driver: fallback to the location of clang if no sysroot,
hard coding /usr makes little sense for mingw-w64.
If we have portable toolchains having /usr breaks that.
If the clang we use is in /usr/bin or /usr/sbin etc this will
still detect as though it was hard coded to /usr

This makes the most sense going forward for mingw-w64 toolchains
on both linux and mac

Xinliang David Li 4dff875259 Disable frame pointer elimination when using -pg
(Re-apply patch after bug fixing)

This diff makes sure that the driver does not pass
-fomit-frame-pointer or -momit-leaf-frame-pointer to
the frontend when -pg is used. Currently, clang gives 
an error if -fomit-frame-pointer is used in combination 
with -pg, but -momit-leaf-frame-pointer was forgotten.
Also, disable frame pointer elimination in the frontend 
when -pg is set.
